 - [x] **B6.** `CLOSE_TAB` ignores `close_tab_mode` (`MainWindow.cpp:1241-1247`). Always treats as `mode=THIS`. "Close other tabs" / "Close tabs to the right" keybinds silently close only the current tab. — fixed in `33b5dee46`
 - [x] **B7.** `INITIAL_SIZE` halves window on HiDPI (`MainWindow.cpp:1429-1433`). Width/height from libghostty are already logical pixels; Qt divides by `devicePixelRatioF()` again. macOS uses unmodified. — fixed in `33b5dee46`
 - [x] **B8.** `MOUSE_VISIBILITY` clobbers cursor shape on un-hide (`MainWindow.cpp:1512-1520`). Sets `Qt::ArrowCursor` on un-hide, destroying the previous shape from `MOUSE_SHAPE`. macOS preserves shape. — fixed in `a48ff0fb8`
-- [ ] **B9.** Performable-action-returns-true: `MOVE_TAB`, `GOTO_TAB`, `GOTO_SPLIT`, `RESIZE_SPLIT`, `EQUALIZE_SPLITS`, `TOGGLE_SPLIT_ZOOM` all unconditionally return `true`, swallowing chords on unsplit/single-tab surfaces. macOS returns false; GTK gates on `tree.getIsSplit()`.
-- [ ] **B10.** `MOVE_TAB` with target=APP moves a tab in arbitrary first window (`MainWindow.cpp:1504`). macOS returns false for app target.

 - [x] **B11.** `RELOAD_CONFIG` only reloads ONE window (`MainWindow.cpp:1410-1414`). Other windows stay on stale config. macOS reloads globally. — fixed in `33b5dee46`
 - [ ] **B12.** `CONFIG_CHANGE` only refreshes chrome (`MainWindow.cpp:1416-1421`). Doesn't push the new config to running surfaces. `applyWindowConfig` only updates tab-bar + theme — `window-decoration`, `fullscreen`, `maximize` changes don't propagate to existing windows.
 - [ ] **B13.** `OPEN_URL` ignores `kind` (`MainWindow.cpp:1471-1480`). `.text` payloads (e.g. config files) open with whatever the desktop says is default for `.txt` (usually a browser). macOS routes `.text` to a text editor.
 - [ ] **B14.** `OPEN_CONFIG` opens via `QDesktopServices::openUrl` without `text` kind hint — same problem.
 - [x] **B15.** `SHOW_CHILD_EXITED` fires unconditionally (`MainWindow.cpp:1379-1387`, `GhosttySurface.cpp:466-498`). macOS gates on `runtime_ms > 0` and `abnormalCommandExitRuntime` config; Qt shows the banner for fast `exit 0` cases. — fixed in `8e8725274`
 - [x] **B16.** `COPY_TITLE_TO_CLIPBOARD` copies the WINDOW title (`MainWindow.cpp:1280-1284`, `:552`), not the surface title. On a multi-tab window, the wrong title gets copied. macOS copies per-surface. — fixed in `33b5dee46`
-- [ ] **B17.** `PROMPT_TITLE` with target=APP is no-op (`MainWindow.cpp:1271`). macOS promotes to `NSApp.mainWindow`.
-- [ ] **B18.** Many actions in `default: return false;` (`MainWindow.cpp:1603-1604`):
-  - `PWD` — breaks new tab/split working-dir inheritance.
-  - `GOTO_WINDOW` — multi-window cycle.
-  - `PRESENT_TERMINAL` — bring-to-front.
-  - `KEY_TABLE` — bindable mode tables silent.
-  - `READONLY` — read-only state silent.
-  - `COLOR_CHANGE` — OSC 4/10/11/12 routing silent.
-  - `RENDER_INSPECTOR` — inspector won't repaint between frames.
-  - `CELL_SIZE` — window won't snap to cell grid.
-  - `SIZE_LIMIT` — never honors min-size from libghostty.
-  - `TOGGLE_BACKGROUND_OPACITY`, `FLOAT_WINDOW`, `SECURE_INPUT`, `UNDO`/`REDO`, `CHECK_FOR_UPDATES`, `TOGGLE_TAB_OVERVIEW`, `TOGGLE_WINDOW_DECORATIONS` — feature gaps (mostly matching GTK).

 - [x] **B27.** Right-click swallowed when program isn't mouse-capturing (`GhosttySurface.cpp:742-745`, `:782-787`). Qt opens its context menu without ever sending the right-press to libghostty. macOS + GTK send press first, only show menu if core didn't consume — so word-select-then-menu can fire. — fixed in `8e8725274`
 - [x] **B28.** Click-to-focus also reports the click to libghostty. macOS + GTK suppress the matching mouse-up. Qt sends both, so a focus-grabbing click is visible to running programs. — fixed in `8e8725274`
 - [x] **B29.** `XkbState` uses default layout, not the live one (`GhosttySurface.cpp:629-641`). User with us+ru layouts gets us-only `unshifted_codepoint` regardless of active group. GTK uses `event.getLayout()`. — fixed in `913f192d8`
-- [ ] **B30.** Wheel: `pixelDelta` ignored, momentum/precision unset (`GhosttySurface.cpp:919-925`). Trackpad on Wayland is notchy; kitty smooth-scroll never engages. macOS uses precise + momentum flags.
-- [ ] **B31.** Drag-drop URL escaping uses bash-only `'\''` (`GhosttySurface.cpp:889-894`). macOS + GTK use a unified `Shell.escape` / `ShellEscapeWriter` that handles backslashes, newlines, and non-POSIX shells.
-- [ ] **B32.** Plain URL drop not distinguished from file drop. `http://...` becomes a quoted argument instead of pasted text.
