 - [x] T60 Fallback fonts, which a user asked for after 0.1.6: `font_fallbacks` in the settings, a list of installed families tried in order for a character Font family lacks, CJK among them; Settings › Appearance lists them under Font family, each an Ely `FontPicker` with a remove button, and an Add button; each saves only when gpui loads it.
 - [x] T61 On Windows the IME's candidate window stays at the cursor, which a user found jumping after 0.1.6: find why it moves, fix the cause, and log what the input handler tells the IME. Not reproduced on the owner's PC, so the owner closed it; the caret the IME is told is logged.
 - [x] T62 Ely's body runs on below the edge she holds, which a user asked for after 0.1.6, where a hop lifted her off the window and left a gap under her collar: her shirt continues down, hidden behind the edge, so a hop shows more of her and never a gap.
-- [ ] T63 A double-click on a session's title renames it, which a user asked for after 0.1.6: the row's title turns into a field, Enter keeps the name, Escape drops it; the name shows in the row, the terminal's header and the window's title over the program's own until renamed again, and an empty name gives the title back to the program; it lives as long as the session.

 ## T63
 
 - Round 1, 3085a94: FAIL. Presses, Enter, Escape, a blur by a press, other rows, closes, retitles, a full reset, long and Unicode names held, and Ely's `ListItem::editor` left other rows as they were; but leaving the app mid-rename blurred the field while the window's focus still pointed at it, the field went, and back in the app the terminal heard no key until pressed. Fixed in ca3809b: a field that closes while it still holds the focus gives it to the shown terminal; a press that took it elsewhere keeps it there.
+- Round 2, ca3809b: PASS. Back in the app after leaving it mid-rename, `a` reached the program with no press first; 18 scenarios held: Enter, Escape, a blur by a press, presses inside the field, switching and opening sessions, renaming two rows, closing the other session, the renamed one or by Cmd-W, Settings' fields and the Git summary keeping their focus, a triple press, a name of spaces and a later program title; check.sh passed with 263 tests. Windows and Linux windows went unexercised.
