T63: a rename's field that closes while it still holds the window's focus gives it to the shown terminal, since a window that goes inactive blurs the field yet keeps the focus there, which left the terminal deaf to keys once the window came back

 - 2026-10-19: fallback fonts, which a user asked for after 0.1.6, since the Chinese and Latin fonts people like seldom come as one: `font_fallbacks` in the settings lists installed families, tried in order for a character Font family lacks, through gpui's `Font::fallbacks`, which CoreText's cascade list, DirectWrite's fallback builder and cosmic-text's chain each honor; the system's own fallback follows the last. On Linux gpui's cosmic-text path keeps the fallback the last character took while it covers the next, so shaping clusters stay whole: with two fallbacks, a character only the second covers carries the next one, which the first covers too, into the second; macOS and Windows choose per character. The owner chose to leave that so. Each family must load as the terminal draws it, as Font family must, so a family gpui would pass over without a word stops the start or the save, the error naming `font_fallbacks`; an empty name is refused. The field is new beside `font_family`, so a settings file from before loads as it was. Settings › Appearance lists them under Family: each an Ely `FontPicker` whose pick replaces it and a button that removes it, then Add fallback, which opens an empty picker whose pick adds one, its button closing it; a refused pick shows the saved family again, as Family's does. Each row keeps an input of its own, and a removal drops the removed row's input and takes the focus away, since Ely's combobox keeps a focused input's text, and an input kept by place would show, and on Enter save, the family removed. Each picker's id is its input's entity, not its place: Ely's combobox keeps its state by id and listens to the input it first met, so a picker keyed by place, after a removal moved the inputs, wrote another row's family into its new input at the next blur. Ligatures and the bundled Nerd Font for private-use icons stand as before; the cursor preview keeps the family alone.
 - 2026-10-19: a user found the IME's candidate box jumping on Windows after 0.1.6. gpui places it, through `ImmSetCompositionWindow` and `ImmSetCandidateWindow`, only when a composition starts, at the caret the terminal reports, the grid cursor's cell from the last frame, hidden or not. On the owner's PC, WeType under powershell.exe and under a status line redrawn every 100 ms put the box at the caret in 23 compositions out of 23, so the owner closed it unreproduced. The terminal logs each caret the input method asks for, at debug, and each move of the caret, at trace, so the next report carries where the box was told to go.
 - 2026-10-19: Ely's shirt and back hair run on below the edge she holds, which a user asked for after 0.1.6, where a hop lifted her whole figure off the window and showed a gap under her collar and hands: both continue down to 340 in the icon's units, 54 below the edge at 286, past her highest lift, a hop of 31 with a press's 0.6 of one on it, so a hop shows more of her and never the gap; at rest the part below the edge lies outside her window and does not show. The shirt moves with her body, the hair with her head, as before; the hair behind her hands fills under them as she lifts.
-- 2026-10-19: a double press on a session's row renames it, which a user asked for after 0.1.6. Ely's `ListItem::editor`, added to Ely for this, draws Ely's text field in the title's place; the row's first press selects the session, as ever, and its second opens the field, holding what the session is called, selected, with the focus. Enter keeps what it holds and gives the focus back to the shown terminal, Escape drops it the same way, and a blur keeps it, as Windows Terminal's tab rename does. A press inside the open field stays the field's: the row would select its session, which takes the focus to the terminal and ends the rename. The name, its ends trimmed, stands over the program's title in the row, the terminal's header and the window's title until renamed again, a program's later titles passing under it; an empty one gives the title back to the program. It lives as long as the session, and notifications keep the program's title. Each program title, each rename and its end are logged.
