UI extension work (tracking issue)

Labels: ui, ui-extensibility

Tracking/discussion issue for planned UI enhancements. NB: being mentioned on the list below is not a guarantee for being done at any specific time scale, nor is the order necessarily indicative of readiness/priority (except perhaps for the smaller follow-up items for multigrid, which I hope to get done pretty soon). Feel free to add stuff.

• multigrid (#8455 merged)
  • improve size handling: non-screen functions should use requested size, not grid allocated size.
  • :term sizing issues (fix terminal_resize)
  • mouse support (#9429)
  • messages on dedicated grid (when not ext_messages)
• floating windows (#6619)
  • for !ext_popupmenu: pum as float (#9530)
  • for ext_popupmenu: add tests for grid anchoring
  • nvim_win_close to close window by id.
  • Ex-commands for floats (#9663)
    • #9920
  • pumblend but for floats (because why not)
• ext_messages (#7466)
• ext_windows: UI control of layout and wincmds (#8707)
• use ext_popupmenu events for wildmenu to support info and pum (#9607)
• ext_statusline (I have some ideas/pre-WIP code...)
• external columns (number, signs) by transmitting wline_T info (no work done)
• "tabgrid" (#7541 but with multigrid)
• transmit UI highlight definitions for ext_popupmenu using hl-Pmenu, etc. (#10504)
  • ensure that we always use concrete rgb colors for default_colors_set
  • allow subscribing non-default groups
• UI control of ext_popupmenu #9445
  • For ext_cmdline maybe nvim_call_function('setcmdpos') already works (check + add docs/test)
