tmux/TODO

- command bits and pieces:
	* use "--" to mark start of command w/ neww etc to avoid quoting
	* why doesn't command-prompt work if made read-only?
	* allow multiple targets: fnmatch for -t/-c, for example detach all
	  clients with -t*
	* add -c for new-session like new-window
	* attach should take a pane and select it as well as attaching
	* ' and " should be parsed the same (eg "\e" vs '\e') in config
	  and command prompt
	* last-pane across sessions
	* exact match operator for targets (or break the substring match
	  and require eg x* instead of just x)

- make command sequences more usable
	* don't require space after ;
	* options for error handling: && and ||?

- options bits and pieces:
	* set-remain-on-exit is a complete hack
	* way to set socket path from config file
	* -fg/-bg/-attr is crap - better just foo-style options which accept
	  fg=,bg=,bright and so on like #[]

- format improvements:
	* option to quote format (#{session_name:quoted})
	* formats need conditions for >0 (for #P)
	* some way to pad # stuff with spaces, #!2T maybe
	* status stuff is redundant with formats

- choose mode improvements:
	* choose-pane command (augment choose-tree to do this?)
	* choose-mode and copy-mode are very similar, make choose-mode a subset?
	* flag to choose-* for sort order
	* choose mode would be better per client than per window
	* two choices (first one then second, for swap-pane and join-pane)

- improve monitor-*:
	* straighten out rules for multiple clients
	* think about what happens across sessions
	* monitor changes within a region
	* perhaps monitor /all/ panes in the window not just one

- panning over window (window larger than visible)

- link panes into multiple windows

- improve mouse support:
	* bind commands to mouse in different areas? 
	* more fine-grained options
	* commands executed when clicking on a pattern (URL)

- hooks!

- warts on current naming:
	* display-time but message-fg/bg/attr
	* list-* vs show-*
	* server-info
	* split-window -> split-pane??

- way to keep a job running just read its last line of output for #()

- better UTF-8 support:
	* #22T can split in the middle of UTF-8 characters!
	* window names and titles
	* message display
	* prompt input
	* multibyte key input

- live update: server started with -U connects to server, requests sessions and
  windows, receives file descriptors

- there are inconsistencies in what we get from old shell and what comes from
  config for new sessions and windows

- multiline status line?

- support title stack, both internally and externally (restore on detach)
	http://docs.freebsd.org/cgi/getmsg.cgi?fetch=1149299+0+archive/2010/freebsd-questions/20100207.freebsd-questions

- last window update time and format for it

- 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

- copy/paste improvements:
	* case insensitive searching
	* incremental searching
	* append to buffer
	* paste w/o trailing whitespace
	* named buffers and allow gaps in the stack
	* command to toggle selection not to move it in copy-mode

- 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)

- way to tag a layout as a number/name

- optimize pane redraws, 20120318184853.GK10965@yelena.nicm.ath.cx

- instead of separate window and session options, just one master options list
  with each option having a type (window or session), then options on window,
  on session, and global. for window options we look window->session->global,
  and for session we look session->global

- maybe keep last layout + size around and if size reverts just put it back

- way to set hints/limits about pane size for resizing

- revamp layouts: they are too complicated, should be more closely integrated,
  should support hints, layout sets should just be a special case of custom
  layouts, and we should support panes that are not attached to a cell at
  all. this could be the time to introduce panelink to replace layout_cell

- use a better termcap internally instead of screen, perhaps xterm

- use screen-256color when started on 256 colour terminal?

- we need a tmux terminfo entry to document the extensions we are using in
  upstream terminfo

- send arrow key sequences for mouse scroll wheel when in alternate screen

- the way pane, window, session destroy is handled is too complicated and the
  distinction between session.c, window.c and server-fn.c functions is not
  clear. could we just have kill_pane(), kill_window(), unlink_window(),
  kill_session() that fix up all data structures (flagging sessions as dead)
  and return a value to say whether clients need to be checked for dead
  sessions? sort of like session_detach now but more so. or some other scheme
  to make it simpler and clearer? also would be nice to remove/rename
  server-fn.c

- more readable way to work out the various things commands need to know about
  the client, notably:
      - is this the config file? (cmdq->c == NULL)
      - is this a command client? (cmdq->c != NULL && cmdq->c->session == NULL)
      - is this a control client?
      - can i do stdin or stdout to this client?
  or even guarantee that cmdq->c != NULL and provide a better way to tell when
  in the config file - then we use cmdq->c if we need a client w/o a session
  else cmd_current_client

- buffer_sample and the choose-* could let UTF-8 through and display it
  properly.

- formats to show if a window is linked into multiple sessions, into multiple
  attached sessions, and is the active window in multiple attached sessions?
