 | Date | Change | Summary |
 |---|---|---|
+| 2026-10-21 | minor | Form dialogs (conditional-format quick rules, New Name, Remove Duplicates, Text to Columns and every other `Dialog::form`) fit their content: OK and Cancel sit in a row under the last field instead of a right-to-left layout that took the screen's whole height and left the buttons floating halfway down |
 | 2026-10-19 | minor | Ctrl+Enter (`range.fill`) gives each cell what typing the input there gives: a General cell gets the automatic number format (`5%`, `$5`, `3/4/2026`, `=TODAY()`) even when it already held a value, and a cell with its own format, a formatted row or column, or Text keeps it. Cells that held a value used to keep General (`5%` showed 0.05), and empty cells took the active cell's format |
 | 2026-10-18 | minor | Keytip letters typed with left Alt held continue the sequence (Alt+H, O, A / Alt+H, O, I ran nothing before: Alt+letter cancelled keytips); other Alt combinations, AltGr and macOS Option are unchanged (#1846) |
 | 2026-10-12 | minor | The File view's recent list tells when each workbook was last changed, read off the UI thread |
