tmux/TODO

- command bits and pieces:
	* allow multiple targets: fnmatch for -t/-c, for example detach all
	  clients with -t*
	* add -c for new-session like new-window
	* ' and " should be parsed the same (eg "\e" vs '\e') in config
	  and command prompt
	* last-pane across sessions
	* list-keys should quote output so that bindings can just be used in
          config file as-is
	* resize-pane -p to match split-window -p

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

- options bits and pieces:
	* way to set socket path from config file

- format improvements:
	* option to quote format (#{q:session_name})
	* some way to pad # stuff with spaces
	* formats to show if a window is linked into multiple sessions, into
	  multiple attached sessions, and is the active window in multiple
	  attached sessions?

- 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)
	* choose modes should ditch the key bindings and just have fixed keys, and
          be more customized to their purpose (d to delete a buffer for choose-buffer,
          a preview of buffer contents, etc)

- 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

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

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

- better UTF-8 support:
	* message display
	* searching in copy mode

- copy/paste improvements:
	* incremental searching
	* paste w/o trailing whitespace
	* command to toggle selection not to move it in copy-mode
	* regex searching
	* copy-pipe should have -x as well
	* searching in copy mode should unwrap lines, so if you search for "foobar"
          then it should be found even if it is now "foo\nbar" (if the WRAP flag
          is set on the line)
	* capture-pane option to preserve spaces but not join lines

- layout stuff
	* way to tag a layout as a number/name
	* maybe keep last layout + size around and if size reverts just put it
	  back
	* 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
	* way to set hints/limits about pane size for resizing
	* panning over window (window larger than visible)
	* a mode where one application can cross two panes (ie x|y, width =
	  COLUMNS/2 but height = ROWS * 2)
	* separate active panes for different clients

- terminfo bits
	* use a better termcap internally instead of screen, perhaps xterm
	* use screen-256color when started on 256 colour terminal?

- code cleanup
	* 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.
	  problem: what about windows in multiple sessions? there are contexts
	  where we do not know which session, or where multiple choices makes
	  no sense... could at least have one global list for all types of
	  global options and keep separate window,session lists
	* 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

- miscellaneous
	* way to keep a job running just read its last line of output for #()
	* link panes into multiple windows
	* 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. likewise, panes and
	  jobs and run-shell and lock command all start with slightly different
	  environments
	* multiline status line? separate command prompt and status line?
	* customizable command aliases -- don't really want a whole alias tree
          and set-alias commands like hooks/options/environ. maybe array
          options, so you set command-alias[0] to foo=bar? array options would
          be useful for other stuff
	* automatic pane logging
	* marks in history, automatically add (move?) one when pane is changed

- hooks
	* more hooks for various things
	* finish after hooks for special commands
	* multiple hooks with the same name?
	* finish hooks for notifys
	* for session_closed, if no sessions at all, perhaps fake up a temporary one
