 - **W6c**: Add search wrap-around notification — `last_wrapped` flag in both editor `SearchState` and viewer `Search`; "Search wrapped" message on wrap in both editor and viewer
 - **W6d**: Editor status bar tab width indicator — `Tab:{width}` in `status_string()`; hardcoded widget defaults verified as dead code (all rendering goes through `render_popup` which uses theme colors)

+### 9.5 Progress Dialogs for File Operations (W7, 2026-07-06)
+
+Foreground copy/move/delete now spawn on a background thread and show the existing `ProgressDialog` (gauge, sparkline, ETA, cancel button) while the operation runs. The event loop polls the result channel every frame and applies the outcome when the thread finishes.
+
+- **DialogState::Progress** variant added — modal progress dialog with live OpHandle progress
+- **PendingProgressOp** tracks kind/sources/destination/result channel/preserve+follow flags
+- **spawn_op_with_progress()** spawns thread + shows modal progress dialog with title "Copying..."/"Moving..."/"Deleting..."
+- **tick_progress()** polls channel via `try_recv()`, handles `Ok(Ok(()))` (success), `Ok(Err(DestExists))` (→ overwrite dialog), `Ok(Err(other))` (→ error dialog), `Empty` (keep waiting), `Disconnected` (→ "thread panicked")
+- **ProgressDialog Cancel key** (Enter when cancel button focused) calls `handle.cancel()`; Tab toggles focus
+- **Wired into app.rs event loop** — `fm.tick_progress()` runs in the timeout branch; re-render triggers every tick while `pending_progress.is_some()` or `tick_progress` completed
+
+All 1381 tests pass, zero warnings, committed `9024b87934`.
