- line mode/char-at-a-time mode a la telnet?
- handle ioctl/termios stuff on window sockets
- figure out once and for all what is going on with backspace and del
      backspace should be translated per the termios setting.
      del passed through?
- window creation/idle time
- profile/optimise, particularly (i suspect) input.c
- could use bsearch all over the place or get rid of smaller tables (clientmsg)
- better errors when creating new windows/sessions (how?)
- Implicitly add exec to the commands for new windows (switch to disable it)
- it would be nice to have multichar commands so you could have C-b K K for
  kill-window to limit accidental presses
- status-fg/status-bg should be able to set attributes: bold, etc
- refer to windows by name etc (duplicates? fnmatch?)
- commands:
 	extend list-clients to list clients attached to a session (-a for all?)
	bring back detach-session to detach all clients on a session?
	clone-session command to link all windows to a new session
- allow fnmatch for -c, so that you can, eg, detach all clients
- bind non prefix keys
- garbage collect window history (100 lines at a time?) if it hasn't been used
  in $x time (need window creation/use times)
- lift SHRT_MAX limits for history
- audit copy/scroll and other modes for problems with very small windows
- split clients into three RB trees by fd: attached/unattached/dead?
  or tailqs? what would be fastest per-char?
- c/p is still borken in some ways
- better mode features: search, back word, forward word, etc
- flags to centre screen in window
- better terminal emulation (identify, insert mode, some other bits)
- when resizing, use history
- audit for leftover/unused code
- activity/bell should be per-window not per-link? what if it is cur win in
  session not being watched?
- tidy up window modes
- problems with force-width when wrapping line in emacs?
- next prev word etc in command prompt; also ^K; also make it support modes
  to support vi. is there something could use for this? editline(3)/readline?
- many more info() displays for various things
- vi half page scroll
- backspace should perhaps wrap backwards over newlines which were not moved
  down by a newline: screen and the OS X terminal does this but xterm and most
  others do not. this might be hard: a flag for each grid line (top bit of size
  maybe)? a single flag is insufficient as can't then tell when to /stop/
  unwrapping
- input.c is too complicated. simplify?
- try change from pass-though model to redraw model (use updated screen
  data). maybe too slow though?
- use a better termcap internally instead of screen, perhaps xterm
- tty.c is a bit ugly
- a command to display the status line briefly when it is turned off
- FAQ "Can I have some examples of cool things I can do with tmux?" -- linkw,
  more??
- kill all but current pane
- fix rxvt cursor fg issue (text under cursor can have non-white fg)
- key handling sucks a bit and needs to be reworked
- some people find first window being 0 rather than 1 is awkward on the
  keyboard. what about a new-window-index option that sets the base at which
  tmux starts numbering new windows, then they can do: set -g new-window-index
  1; bind 0 selectw -t:10
- some way to change status line colours based on something? command?
- client sx/sy should be in tty, then can let the terminal wrap at edge
  to allow xterm to pick up it should be one line for its c/p
- should be able to move to a hidden pane and it would be moved into view. pane
  number in status line/top-right would be cool for this
- command to run something without a window at all - output to
  window-more. what for? isnt this the same as doing it w/ splitw/neww now?
- command to purge window history? or apply history-limit changes?
- clone session command
- make command sequences more usable: don't require space around ;, handle
  errors better
- would be nice if tmux could be the shell (tmux attach, but hard link to tmux
  binary as "tmuxsh" or wrapper script?) -- problems with tty dev permeissions
- 88 colour support; new grid cell flag, and 256<->88 88<->16 translation tables
- UTF-8 combining characters don't work. store in one cell - pointer to table
  of chains. bit of a hack and would mean max of 65536 per screen. OR maybe
  utf8 should work differently; could store as multiple cells, 1 of width >0
  and n of width 0, then translate cursor indexes on-the-fly would need to
  adjust all cursor movement and also handle different width lines properly.

(hopefully) for 0.7, in no particular order:
- swap-pane-up, swap-pane-down (maybe move-pane-*)
- move-pane (to window) (maybe break-pane?)
- command: copy-buffer -s src-session -t dst-session -a src-index -b dst-index
  (copy from other session)
- flag to scroll-mode/copy-mode to automatically scroll up a page
- key to switch to copy mode from scroll mode
- document suspend-client
- document command sequences
- document find-window
- document split-window -p and -l
- attach should have a flag to create session if it doesn't exist
