It's not necessarily guaranteed that items in this TODO file +will ever get implemented. + +It is asked therefore, that anyone thinking of undertaking a task in this +TODO file, email tmux-users@lists.sf.net to discuss the feature. + +Thie file is split up between tmux user interface (UI) issues, and terminal +compatibility issues. + +TMUX UI ISSUES +============== + +- implicitly add exec to the commands for new windows (switch to disable it)? +- bring back detach-session to detach all clients on a session? +- allow fnmatch for -c, so that you can, eg, detach all clients +- garbage collect window history (100 lines at a time?) if it hasn't been used + in $x time +- flags to centre screen in window +- activity/bell should be per-window not per-link? what if it is cur win in + session not being watched? +- 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 +- support other mouse modes (highlight etc) and use it in copy mode +- set-remain-on-exit is a bit of a hack, some way to do it generically? +- would be nice to be able to use "--" to mark start of command w/ neww etc + to avoid quoting +- make command sequences more usable: don't require space after ;, handle + errors better +- choice and more mode would be better per client than per window? +- hooks to which commands may be attached, for example: tmux add-hook + "new-session" if-shell "[ -e $HOME/.tmux-session.conf ]" source-file + $HOME/.tmux-session.conf +- way to set socket path from config file +- warts on current naming: + - display-time but message-fg/bg/attr + - list-* vs show-* + - server-info + - up-pane/down-pane/swap-pane -U/swap-pane -D vs next-*/previous-* + - split-window -> split-pane?? +- some way to force a screen to use the entire terminal even if it is forced + to be smaller by other clients. pan smaller terminal?
