No shortcuts, hacks, or compromises.   - Support all features and API of normal windows, plus more.6427894# 8455Multigrid: "windows drawn on separate grids"   - Windows are logically isolated internally.   - Windows are sent to UIs as distinct objects, so that UIs can control     layout instead of being stuck with the classic TUI layout.   - Per-window font-size, dimenions, line-spacing.   - Compositor: Internal subsystem for composing grids.3855204# 6917UIEnter, UILeave788 BCBB# 9923ui: ": syn blend=", 'winblend'7cf7c0a(#) ui: 'redrawdebug' option for flexible debugging of redrawing5C 836 D2# 9607wildoptions=pum (enabled by default)37 f8df8# 9571UI: 'pumblend' option for semi-transparent popupmenuC 403 A 95# 9446Visual: highlight char-at-cursor   - Traditionally Vim's visual selection does "reverse mode", which     perhaps conflicts with the non-blinking block cursor. But     'guicursor' defaults to a vertical bar for selection=exclusive, and     this confuses users who expect to see the text highlighted.  : terminalFC  (DC9)# 8550autocmds: TermEnter, TermLeaveD 13803 f# 9810keymap, terminal: more keycodes3b  (f)# 9535: terminal: Fix F1-F4 key codes2d4a  (e)# 10370: ls: show "R", "F" for terminal- jobsFD0FD 75# 9966terminal: swap priority of terminal, editor highlights7bb 858 c# 9494libvterm 0.1  TUI3afb 397syntax, TUI: support "strikethrough"ccbcd 39# 9408TUI: "title stacking" unconditionally(f)(#) TUI: detect background color, set bg=dark / light(f) *************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************** (a)# 9097TUI: handle Smulx extension capability (extended underline)424 DDD0# 10205TUI: support rgba background det ection(9b)# 9601TUI: italics in tmux, Terminal.appF6FB 370# 9793keymap: support more (keypad) keycodes(e)# 9423TUI: Konsole DECSCUSR fixup  : checkhealthD0FD 66 bhealth / provider.vim: check curl HTTPS support(c)  a# 10490checkhealth: try yarn if npm is missing(A4)# 9929health: check if tmux enabled true colorsec5a4d8# 9548checkhealth: validate locale  providers (clipboard, python, etc.):96 be8a2# 10161Allow reloading providers (useful for UIs / clients)(db3c)# 9487provider: improve error message if provider is missing  Various:36762 A0# 9295signs: support multiple columns801 fe 79# 10382eval: wait () (wait for any condition)9df3a 67# 10400MsgArea highlight; message grida9bea8c# 10790keymap : allow modifiers to multibyte chars, like25 E0A 44# 10878# 4448paste: redesign (10 x   faster pasting; extensible vim.paste Lua hook)EF 5037 e# 9706autocmd : introduce "   once" feature175398 f# 9616add CompleteChanged autocmd7fcf2f9# 9717TextYankPost: add v: event ["inclusive"]3A 699 A7# 8364termdebug.vim pluginCA1CE 59# 9709performance: use os_copy to create backupsed0e 96 cman.vim: set 'linebreak'70 f 6939# 9564events: add "Signal" eventf 89 d0d8# 9568inccommand: auto-disable if folding is slow  FIXES:(BB)  b# 10584process_stop: uv: do not close stdin first / explicitlye 50 aa2a# 10117normal: Don't exit CTRL-O mode after processing K_EVENT(fa)  c# 9504: recover: Fix crash on non-existent * .swp(5A)  d4# 9507screen: don't unconditionally clear messages on window scroll149 DCBF# 10021channel: refactor events, prevent recursive invocation of events(D)  FF 73# 10107Fix multiple c_CTRL-D showing statusline(b)  a7b7# 10103Fix wildmode=list, full and display =msgsep interaction0be6d3c# 9634fsync: Ignore ENOTSUP.

This logical contradiction was already fixed     for remote UIs (#C 236 e 80). Fixing it also for the TUI avoids     problems on Windows, simplifies the logic, and avoids races like# 9959.
