- option to show bells visually
- window-status command to show current window info in status line
- H/M/L commands in copy mode with vi-keys, for jumping to the top/middle/last line on the screen
- if the server is started with IDENTIFY_UTF8 then set the global utf8 option?
- I think there are potential leaks in the prompt code if a new prompt is created without the
callback for the old being cleared; this might be quite hard to hit, lock-server seems the only
candidate
- tidy up and prioritise todo list ;-)
