+CHANGES FROM 1.5 TO 1.6, 23 January 2012
+
+* Extend the mode-mouse option to add a third choice which means the mouse
+  does not enter copy mode.
+* Add a -r flag to switch-client to toggle the client read-only flag.
+* Add pane-base-index option.
+* Support \ for line continuation in the configuration file.
+* Framework for more powerful formatting of command output and use it for
+  list-{panes,windows,sessions}. This allows more descriptive replacements
+  (such as #{session_name}) and conditionals.
+* Mark dead panes with some text saying they are dead.
+* Reject $SHELL if it is not a full path.
+* Add -S option to refresh-client to redraw status line.
+* Add an else clause for if-shell.
+* Try to resolve relative paths for loadb and saveb (first, using client
+  working directory, if any, then default-path or session working directory).
+* Support for \e[3J to clear the history and send the corresponding
+  terminfo code (E3) before locking.
+* When in copy mode, make repeat count indicate buffer to replace, if used.
+* Add screen*:XT to terminal-overrides for tmux-in-tmux.
+* Status-line message attributes added.
+* Move word-separators to be a session rather than window option.
+* Change the way the working directory for new processes is discovered. If
+  default-path isn't empty, it is used. Otherwise, if a new window is created
+  from the command-line, the working directory of the client is used. If not,
+  platform specific code is used to retrieve the current working directory
+  of the process in the active pane. If that fails, the directory where the
+  session was created is used, instead.
+* Do not change the current pane if both mouse-select-{pane,window} are
+  enabled.
+* Add \033[s and \033[u to save and restore cursor position.
+* Allow $HOME to be used as default-path.
+* Add CNL and CPL escape sequences.
+* Calculate last position correctly for UTF-8 wide characters.
+* Add an option allow-rename to disable the window rename escape sequence.
+* Attributes for each type of status-line alert (ie bell, content and
+  activity) added. Therefore, remove the superfluous options
+  window-status-alert-{attr,bg,fg}.
+* Add a -R flag to send-keys to reset the terminal.
+* Add strings to allow the aixterm bright colours to be used when
+  configuring colours.
+* Drop the ability to have a list of keys in the prefix in favour of two
+  separate options, prefix and prefix2.
+* Flag -2 added to send-prefix to send the secondary prefix key.
+* Show pane size in top right of display panes mode.
+* Some memory leaks plugged.
+* More command-prompt editing improvements.
+* Various manpage improvements.
+* More Vi mode improvements.
+
+CHANGES FROM 1.4 TO 1.5, 09 July 2011
+
+* Support xterm mouse modes 1002 and 1003.
+* Change from a per-session stack of buffers to one global stack. This renders
+  copy-buffer useless and makes buffer-limit now a server option.
+* Fix most-recently-used choice by avoiding reset the activity timer for
+  unattached sessions every second.
+* Add a -P option to new-window and split-window to print the new window or
+  pane index in target form (useful to pass it into other commands).
+* Handle a # at the end of a replacement string (such as status-left)
+  correctly.
+* Support for UTF-8 mouse input (\033[1005h) which was added in xterm 262.
+  If the new mouse-utf8 option is on, UTF-8 mouse input is enabled for all
+  UTF-8 terminals. The option defaults to on if LANG etc are set in the same
+  manner as the utf8 option.
+* Support for HP-UX.
+* Accept colours of the hex form #ffffff and translate to the nearest from the
+  xterm(1) 256-colour set.
+* Clear the non-blocking IO flag (O_NONBLOCK) on the stdio file descriptors
+  before closing them (fixes things like "tmux ls && cat").
+* Use TMPDIR if set.
+* Fix next and previous session functions to actually work.
+* Support -x and -y for new-session to specify the initial size of the window
+  if created detached with -d.
+* Make bind-key accept characters with the top-bit-set and print them as octal.
+* Set $TMUX without the session when background jobs are run.
+* Simplify the way jobs work and drop the persist type, so all jobs are
+  fire-and-forget.
+* Accept tcgetattr/tcsetattr(3) failure, fixes problems with fatal() if the
+  terminal disappears while locked.
+* Add a -P option to detach to HUP the client's parent process (usually causing
+  it to exit as well).
+* Support passing through escape sequences to the underlying terminal by using
+  DCS with a "tmux;" prefix.
+* Prevent tiled producing a corrupt layout when only one column is needed.
+* Give each pane created in a tmux server a unique id (starting from 0), put it
+  in the TMUX_PANE environment variable and accept it as a target.
+* Allow a start and end line to be specified for capture-pane which may be
+  negative to capture part of the history.
+* Add -a and -s options to lsp to list all panes in the server or session
+  respectively. Likewise add -s to lsw.
+* Change -t on display-message to be target-pane for the #[A-Z] replacements
+  and add -c as target-client.
+* The attach-session command now prefers the most recently used unattached
+  session.
+* Add -s option to detach-client to detach all clients attached to a session.
+* Add -t to list-clients.
+* Change window with mouse wheel over status line if mouse-select-window is on.
+* When mode-mouse is on, automatically enter copy mode when the mouse is
+  dragged or the mouse wheel is used. Also exit copy mode when the mouse wheel
+  is scrolled off the bottom.
+* Provide #h character pair for short hostname (no domain).
+* Don't use strnvis(3) for the title as it breaks UTF-8.
+* Use the tsl and fsl terminfo(5) capabilities to update terminal title and
+  automatically fill them in on terminals with the XT capability (which means
+  their title setting is xterm-compatible).
+* Add a new option, mouse-resize-pane. When on, panes may be resized by
+  dragging their borders.
+* Fix crash by resetting last pane on {break,swap}-pane across windows.
+* Add three new copy-mode commands - select-line, copy-line, copy-end-of-line.
+* Support setting the xterm clipboard when copying from copy mode using the
+  xterm escape sequence for the purpose (if xterm is configured to allow it).
+* Support xterm(1) cursor colour change sequences through terminfo(5) Cc
+  (set) and Cr (reset) extensions.
+* Support DECSCUSR sequence to set the cursor style with two new terminfo(5)
+  extensions, Cs and Csr.
+* Make the command-prompt custom prompts recognize the status-left option
+  character pairs.
+* Add a respawn-pane command.
+* Add a couple of extra xterm-style keys that gnome terminal provides.
+* Allow the initial context on prompts to be set with the new -I option to
+  command-prompt. Include the current window and session name in the prompt
+  when renaming and add a new key binding ($) for rename session.
+* Option bell-on-alert added to trigger the terminal bell when there is an
+  alert.
+* Change the list-keys format so that it shows the keys using actual tmux
+  commands which should be able to be directly copied into the config file.
+* Show full targets for lsp/lsw -a.
+* Make confirm-before prompt customizable with -p option like command-prompt
+  and add the character pairs #W and #P to the default kill-{pane,window}
+  prompts.
+* Avoid sending data to suspended/locked clients.
+* Small memory leaks in error paths plugged.
+* Vi mode improvements.
+
+CHANGES FROM 1.3 TO 1.4, 27 December 2010
+
+* Window bell reporting fixed.
+* Show which pane is active in the list-panes output.
+* Backoff reworked.
+* Prevent the server from dying when switching into copy mode when already
+  in a different mode.
+* Reset running jobs when the status line is enabled or disabled.
+* Simplify xterm modifier detection.
+* Avoid crashing in copy mode if the screen size is too small for the
+  indicator.
+* Flags -n and -p added to switch-client.
+* Use UTF-8 line drawing characters on UTF-8 terminals, thus fixing some
+  terminals (eg putty) which disable the vt100 ACS mode switching sequences
+  in UTF-8 mode. On terminals without ACS, use ASCII equivalents.
+* New server option exit-unattached added.
+* New session option destroy-unattached added.
+* Fall back on normal session choice method if $TMUX exists but is invalid
+  rather than rejecting.
+* Mark repeating keys with "(repeat)" in the key list.
+* When removing a pane, don't change the active pane unless the active pane
+  is actually the one being removed.
+* New command last-pane added.
+* AIX fixes.
+* Flag -a added to unbind-key.
+* Add XAUTHORITY to update-environment.
+* More info regarding window and pane flags is now shown in list-*.
+* If VISUAL or EDITOR contains "vi" configure mode-keys and status-key to vi.
+* New window option monitor-silence and session option visual-silence added.
+* In the built-in layouts distribute the panes more evenly.
+* Set the default value of main-pane-width to 80 instead of 81.
+* Command-line flag -V added.
+* Instead of keeping a per-client prompt history make it global.
+* Fix rectangle copy to behave like emacs (the cursor is not part of the
+  selection on the right edge but on the left it is).
+* Flag -l added to switch-client.
+* Retrieve environment variables from the global environment rather than
+  getenv(3), thus allowing them to be updated during the configuration file.
+* New window options other-pane-{height,width} added.
+* More minor bugs fixed and manpage improvements.
+
+CHANGES FROM 1.2 TO 1.3, 18 July 2010
+
+* New input parser.
+* Flags to move through panes -UDLR added to select-pane.
+* Commands up-pane, and down-pane removed, since equivalent behaviour is now
+  available through the target flag (-t:+ and -t:-).
+* Jump-forward/backward in copy move (based on vi's F, and f commands).
+* Make paste-buffer accept a pane as a target.
+* Flag -a added to new-window to insert a window after an existing one, moving
+  windows up if necessary.
+* Merge more mode into copy mode.
+* Run job commands explicitly in the global environment (which can be modified
+  with setenv -g), rather than with the environment tmux started with.
+* Use the machine's hostname as the default title, instead of an empty string.
+* Prevent double free if the window option remain-on-exit is set. 
+* Key string conversions rewritten.
+* Mark zombie windows as dead in the choose-window list.
+* Tiled layout added.
+* Signal handling reworked.
+* Reset SIGCHLD after fork to fix problems with some shells.
+* Select-prompt command removed. Therefore, bound ' to command-prompt -p index
+  "select-window -t:%%" by default.
+* Catch SIGHUP and terminate if running as a client, thus avoiding clients from
+  being left hanging around when, for instance, a SSH session is disconnected.
+* Solaris 9 fixes (such as adding compat {get,set}env(3) code).
+* Accept none instead of default for attributes.
+* Window options window-status-alert-{alert,bg,fg} added.
+* Flag -s added to the paste-buffer command to specify a custom separator.
+* Allow dragging to make a selection in copy mode if the mode-mouse option is
+  set.
+* Support the mouse scroll wheel.
+* Make pipe-pane accept special character sequences (eg #I).
+* Fix problems with window sizing when starting tmux from .xinitrc.
+* Give tmux sockets (but not the containing folder) group permissions.
+* Extend the target flags (ie -t) to accept an offset (for example -t:+2), and
+  make it wrap windows, and panes.
+* New command choose-buffer added.
+* New server option detach-on-destroy to set what happens to a client when the
+  session it is attached to is destroyed. If on (default), the client is
+  detached. Otherwise, the client is switched to the most recently active of
+  the remaining sessions.
+* The commands load-buffer, and save-buffer now accept a dash (-) as the file
+  to read from stdin, or write to stdout.
+* Custom layouts added.
+* Additional code reduction, bug fixes, and manpage enhancements.
+
+CHANGES FROM 1.1 TO 1.2, 10 March 2010
+
+* Switch to libevent.
+* Emulate the ri (reverse index) capability, ergo allowing tmux to at least
+  start on Sun consoles (TERM=sun, or sun-color).
+* Assign each entry a number, or lowercase letter in choose mode, and accept
+  that as a shortcut key.
+* Permit top-bit-set characters to be entered in the status line.
+* Mark no-prefix keys with (no prefix), rather than [] in list-keys.
+* New command show-messages (alias showmsgs), and new session option
+  message-limit, to show a per-client log of status lines messages up to the
+  number defined by message-limit.
+* Do not interpret #() for display-message to avoid leaking commands.
+* New window options window-status-format, and window-status-current-format to
+  control the format of each window in the status line.
+* Add a -p flag to display-message to print the output, instead of displaying
+  it in the status line.
+* Emulate il1, dl1, ich1 to run with vt100 feature set.
+* New command capture-pane (alias capturep) to copy the entire pane contents
+  to a paste buffer.
+* Avoid duplicating code by adding a -w flag to set-option, and show-options to
+  set, and show window options. The commands set-window-option, and
+  show-window-options are now aliases.
+* Panes can now be referred to as top, bottom, top-left, etc.
+* Add server-wide options, which can be set with set-option -s, and shown with
+  show-options -s.
+* New server option quiet (like -q from the command line).
+* New server option escape-time to set the timeout used to detect if escapes
+  are alone, part of a function key, or meta sequence.
+* New session options pane-active-border-bg, pane-active-border-fg,
+  pane-border-bg, and pane-border-fg to set pane colours.
+* Make split-window accept a pane target, instead of a window.
+* New command join-pane (alias joinp) to split, and move an existing pane into
+  the space (the opposite of break-pane), thus simplifying calls to
+  split-window, followed by move-window.
+* Permit S- prefix on keys for shift when the terminal/terminfo supports them.
+* Window targets (-t flag) can now refer to the last window (!), next (+), and
+  previous (-) window by number.
+* Mode keys to jump to the bottom/top of history, end of the next word, scroll
+  up/down, and reverse search in copy mode.
+* New session option display-panes-active-colour to display the active pane in
+  a different colour with the display-panes command.
+* Read the socket path from $TMUX if it's present, and -L, and -S are not
+  given.
+* Vi-style mode keys B, W, and E to navigate between words in copy mode.
+* Start in more mode when configuration file errors are detected.
+* Rectangle copy support added.
+* If attach-session was specified with the -r flag, make the client read-only.
+* Per-window alternate-screen option.
+* Make load-buffer work with FIFOs.
+* New window option word-separators to set the characters considered as word
+  separators in copy mode.
+* Permit keys in copy mode to be prefixed by a repeat count, entered with [1-9]
+  in vi mode, or M-[1-9] in emacs mode.
+* utf8 improvements.
+* As usual, additional code reduction, bug fixes, and manpage enhancements.

-tmux offers several advantages over screen:
+* How is tmux different from GNU screen?
 
-- a clearly-defined client-server model: windows are independent entities which
-  may be attached simultaneously to multiple sessions and viewed from multiple
-  clients (terminals), as well as moved freely between sessions within the same
-  tmux server;
-- a consistent, well-documented command interface, with the same syntax
-  whether used interactively, as a key binding, or from the shell;
-- easily scriptable from the shell;
-- multiple paste buffers;
-- choice of vi or emacs key layouts;
-- an option to limit the window size;
-- a more usable status line syntax, with the ability to display the first line
-  of output of a specific command;
-- a cleaner, modern, easily extended, BSD-licensed codebase.
+tmux and GNU screen have many similarities. Some of the main differences I am
+aware of are (bearing in mind I haven't used screen for a few years now):
 
-There are still a few features screen includes that tmux omits:
+- tmux uses a client-server model. Each server has single Unix domain socket in
+  /tmp and within one server there are multiple sessions which may be attached
+  to multiple clients (terminals).
 
-- builtin serial and telnet support; this is bloat and is unlikely to be added
-  to tmux;
-- wider platform support, for example IRIX and HP-UX, and for odd terminals.
+  This has advantages, notably: windows may be linked simultaneously to
+  multiple sessions; windows may be moved freely between sessions; and a client
+  may be switched between sessions easily (C-b D). There is one major
+  disadvantage: if the server crashes, game over, all sessions die. In
+  practice, however, tmux is quite stable and gets more so as people report any
+  bugs they hit :-).
+
+  This model is different from screen, where typically each new screen instance
+  is independent. tmux supports the same behaviour by using multiple servers
+  with the -L option but it is not typically recommended.
+
+- Different command interfaces. One of the goals of tmux is that the shell
+  should be easily usable as a scripting language - almost all tmux commands
+  can be used from the shell and behave identically whether used from the
+  shell, from a key binding or from the command prompt. Personally I also find
+  tmux's command interface much more consistent and clearer, but this is
+  subjective.
+
+- tmux calls window names (what you see in the status line) "names", screen
+  calls them "titles".
+
+- tmux has a multiple paste buffers. Not a major one but comes in handy quite a
+  lot.
+
+- tmux supports automatically renaming windows to the running application
+  without gross hacks using escape sequences. Its even on by default.
+
+- tmux has a choice of vi or emacs key layouts. Again, not major, but I use
+  emacs so if tmux did support only one key set it would be emacs and then all
+  the vi users would get humpy. Key bindings may be completely reconfigured in
+  any case.
+
+- tmux has an option to limit the window size.
+
+- tmux has search in windows (C-b f).
+
+- The window split (pane) model is different. tmux has two objects, windows and
+  panes; screen has just windows. This difference has several implications:
+
+  * In screen you can have a window appear in several layouts, in tmux a pane
+  can only be in one window (fixing this is a big todo item but quite
+  invasive).
+
+  * tmux layouts are immutable and do not get changed unless you modify them.
+
+  * In tmux, all panes are closed when you kill a window.
+
+  * tmux panes do not have individual names, titles and so on.
+
+  I think tmux's model is much easier to manage and navigate within a window,
+  but breaking panes off from and joining them to windows is more clumsy.
+
+  tmux also has support for preset pane layouts.
+
+- tmux's status line syntax is more readable and easier to use. I think it'd be
+  hard for anyone to argue with this. tmux doesn't support running a command
+  constantly and always using the last line of its output, commands must be run
+  again each time.
+
+- tmux has modern, easily extended code. Again hard to argue screen is better
+  if you have looked at the code.
+
+- tmux depends on libevent. I don't see this as a disadvantage: libevent is
+  small and portable, and on modern systems with current package management
+  systems dependencies are not an issue. libevent brings advantages in code
+  simplicity and performance.
+
+- screen allows the window to be bigger than the terminal and can pan around
+  it. tmux limits the size to the largest attached client. This is a big todo
+  item for tmux but it is not trivial.
+
+- screen has builtin serial and telnet support; this is bloat and is unlikely
+  to be added to tmux.
+
+- screen has support for updating utmp. Nobody has really come up with a clean,
+  portable way to do this without making tmux setuid or setgid yet.
+
+- Environment handling is different.
+
+- tmux tends to be more demanding on the terminal so tends to show up terminal
+  and application bugs which screen does not.
+
+- screen has wider platform support, for example IRIX, and for odd terminals.

+* What is the best way to display the load average? Why no #L?

+X:
+
+uptime|awk '{split(substr($0, index($0, "load")), a, ":"); print a[2]}'
+
+* How do I attach the same session to multiple clients but with a different
+  current window, like screen -x?
+
+One or more of the windows can be linked into multiple sessions manually with
+link-window, or a grouped session with all the windows can be created with
+new-session -t.
+
+* Ctrl and arrow keys doesn't work in putty! What do I do?
+
+putty inverts the sense of the cursor key mode on ctrl, which is a bit hard for
+tmux to detect properly. To get ctrl keys right, change the terminfo settings
+so kUP5 (Ctrl-Up etc) are the adjusted versions, and disable smkx/rmkx so tmux
+doesn't change the mode. For example with this line in .tmux.conf (assuming you
+have TERM set to xterm):
+
+set -g terminal-overrides "xterm*:kLFT5=\eOD:kRIT5=\eOC:kUP5=\eOA:kDN5=\eOB:smkx@:rmkx@"
+
+Note that this will only work in tmux 1.2 and above.
+
+* How can I blank the tmux window?
+
+GNU screen has a feature whereby it will blank the screen after a period of
+inactivity. To do the same thing in tmux, use the lock-command setting, for
+example (with GNU bash):
+
+set -g lock-command 'tput civis && read -s -n1'
+
+This will remove the cursor and tell the shell to quit once a key has been
+pressed. For zsh, use "read -s -k1".
+
+In addition, it's possible to have both blanking and locking (for instance via
+lock(1) or vlock(1)) by using the following:
+
+bind x set lock-command '/usr/bin/vlock' \; lock-client \; set lock-command 'tput civis && read -s -n1'
+
+* How can I open a new window in the same directory as the current window?
+
+One option is to just run "TMUX= tmux" in the window. However, this only works if no
+command is running, so that you can input the command.
+
+A workaround is to let tmux know about the current path through an environment
+variable. To do so, use the following command:
+
+    [ -n "$TMUX" ] && tmux setenv TMUXPWD_$(tmux display -p "#I") $PWD
+
+Which sets TMUXPWD_i (where i is the number of the current window) to the path
+of the current directory. This command can be added to PS1, for example:
+
+    PS1='$([ -n "$TMUX" ] && tmux setenv TMUXPWD_$(tmux display -p "#I") $PWD)\h$ '
+
+When a new window is created, the shell should be asked to change
+directory. You can define a new binding (for example, if using GNU bash):
+
+    bind-key C-c run-shell 'tmux neww "cd $(tmux display -p "\$TMUXPWD_#I"); exec bash"'
+
+This solution will work even if a command is currently running in the terminal,
+but it will not work from a window that has just been swapped with another
+because TMUXPWD_i will not be updated after a swap. However, once a new prompt
+is displayed, TMUXPWD_i is updated properly.
+
+* tmux doesn't start with "daemon failed"
+
+tmux shows something similar to this when started:
+
+    fatal: server_start: daemon failed: No such file or directory
+    fatal: main_dispatch: imsg_read failed
+
+A possible reason is that /dev/null is not a character device or is otherwise
+inaccessible.
+
+Check with:
+
+    file /dev/null
+    ls -l /dev/null
+
+If it is not a character device or has incorrect permissions, it can typically
+be recreated with:
+
+    cd /dev && rm null && ./MAKEDEV null
+
+* vim displays reverse video instead of italics, while less displays italics
+  (or just regular text) instead of reverse. What's wrong?
+
+Screen's terminfo description lacks italics mode and has standout mode in its
+place, but using the same escape sequence that urxvt uses for italics. This
+means applications (like vim) looking for italics will not find it and might
+turn to reverse in its place, while applications (like less) asking for
+standout will end up with italics instead of reverse. To make applications
+aware that tmux supports italics and to use a proper escape sequence for
+standout, you'll need to create a new terminfo file with modified sgr, smso,
+rmso, sitm and ritm entries:
+
+	$ mkdir $HOME/.terminfo/
+	$ screen_terminfo="screen"
+	$ infocmp "$screen_terminfo" | sed \
+	  -e 's/^screen[^|]*|[^,]*,/screen-it|screen with italics support,/' \
+	  -e 's/%?%p1%t;3%/%?%p1%t;7%/' \
+	  -e 's/smso=[^,]*,/smso=\\E[7m,/' \
+	  -e 's/rmso=[^,]*,/rmso=\\E[27m,/' \
+	  -e '$s/$/ sitm=\\E[3m, ritm=\\E[23m,/' > /tmp/screen.terminfo
+	$ tic /tmp/screen.terminfo
+
+And tell tmux to use it in ~/.tmux.conf:
+	
+	set -g default-terminal "screen-it"
+
+If your terminal supports 256 colors, use:
+
+	$ screen_terminfo="screen-256color"
+
+instead of "screen". See the FAQ entry about 256 colors support for more info.
+Also note that tmux will still display reverse video on terminals that do not
+support italics.
+
+If your urxvt cannot display italics at all, make sure you have an italics
+capable font enabled, for example, add to ~/.Xdefaults:
+
+	urxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true

+- link panes into multiple windows
+- bells should be passed between sessions with visual-bell etc
+- use screen-256color when started on 256 colour terminal??
+- if-shell/run-shell should block further command execution in the same command
+  sequence until its shell exits, to allow them to be used from the config file
+- better session sharing: create-socket command to create socket somewhere (-r
+  flag for readonly)
+- multiline status line (no?)
+- flag for absolute pane size to resize-pane
+- sanity check input to socket
+- support title stack, both internally and externally
+	http://docs.freebsd.org/cgi/getmsg.cgi?fetch=1149299+0+archive/2010/freebsd-questions/20100207.freebsd-questions
+- command to show status line information briefly when it is off
+- some way to pad # stuff with spaces, #!2T maybe
+- a binding to "scroll down and exit at bottom" copy mode
+- some way to pass keystrokes in copy mode through to underlying window
+- last window update time and # replacement for it for display-message
+- find-window across sessions - other ways to make session handling easier?
+- ' and " should be parsed the same (eg "\e" vs '\e') in config and command
+  prompt?
+- command to toggle selection not to move it in copy-mode
+- why are alerts per-winlink? try per window?
+- audit of escape sequence support vs xterm
+- support binding keys to mouse (mouse-select-pane -> mouse-keys or something,
+  mouse click == select-pane -t %%, mouse scroll up == copy-mode)
+- something for -t "last window in session" so a session can be used as a stack
+- synchronous commands - client sends cmd and blocks, neww/splitw saves client
+  ptr then when program inside died, sends MSG_SOMETHING with wait status to
+  client
+- documentation improvements - rlpowell's tutorial - build instructions
+- bind commands to key sequences? -- make it so ALL keys go through a table,
+  first an implicit table in which C-b is the only default binding to a
+  command that says "next key from $othertable" and so on. means -n can
+  go away as well
+- monitor, bell etc should monitor /all/ panes in the window not just one
+- a history of commands that can be reversed (reverse member of each command,
+  and a buffer) info() when changing to same window
+- way to add dest for break-pane; maybe some easier way to unbreak-pane
+- case insensitive searching
+- option to move status line to top
+- configurable borders and empty space filler for when panes < window?
+- mouse-select-pane will screw up with !MODE_MOUSE_STANDARD (it sets the
+  flag on w/o checking the others before calling tty_update_mode)
 - multiple keys could be done with tables, ie have prefixes go and instead
 	bind -n ^A prefix-table "default"
-  where prefix-table sets command lookup table and sets prefix flag, then next key
-  is looked up in that table
-- check fix UTF-8 and split-window? should be okay
-- UTF-8 should be a pointer into a combined string buffer
-- check irssi (term_charset) works with UTF-8
-- rectangle copy/paste
-- half page/up down are missing from key table
-- support esc-esc to quit in modes
+  where prefix-table sets command lookup table and sets prefix flag, then next
+  key is looked up in that table
+- pass shell commands as argv rather than strings, allow them to be specified
+  in commands without quotes
+- a command to choose from a generic list, so you can do eg
+  choose-list -l Abc,Moo,Blah "run-shell 'sh /my/choose/script %%'"
+- numeric prefix in copy mode should be paste buffer for C-w
+- named buffers and allow gaps in the stack
+- get rid of separate UTF-8 cell stuff: add 1 byte to cell and store BMP as
+  uint16_t+3 bits of flags. anything <=0xffff is Unicode, higher are used to
+  build tree of combined characters/non-BMP (LRU dropped when full)
+- entry in FAQ about what to do when someone does mkdir /tmp/tmux-1000
+- show size under pane number in display-panes mode
+- monitor-activity is broken in several ways with multiple clients
+- monitor-activity should be more powerful (eg set a region)
+- maybe a way to put pane names instead of window names in status line
+- support for borderless panes
+- run-shell/if-shell should support status_replace stuff
+- wait-pane command or another way to make it synchronous/wait for command to
+  finish
+- last-pane across sessions
+- attach should take a pane and select it as well as attaching
+- should default-path be a window option?
+- option to put status line at top (why?)
+- panes should have names like windows
+- command-prompt doesn't work if made read-only. why?
+- option to quote format eg #{session_name:quoted}
+- formats need to be used for much much more stuff!
+- formats need conditions for >0 (for #P)
+- flags to find-window to select what is searched (title, name, content, history)
+- fetch full command line on !Linux, and add option to strip prefixes
+  such as "sh " "/bin/sh " etc etc
+- synchronize-windows option
+- possibly support rxvt-unicode extended mouse input (1015)
+- append to buffer in copy mode
+* We need a tmux terminfo entry to document the extensions we are using in
+  upstream terminfo. Must NOT change (only add or remove) anything from
+  TERM=screen so we can fallback!
