Replace the simple cycleTheme() with a modal dialog that shows all
19 themes with color swatches, live preview on Up/Down navigation,
and commit/revert on Enter/Esc.
Changes:
- Add modalThemeSelect kind to modalKind enum
- Add themeSelectorState struct + field to Model
- Add openThemeSelector() replacing cycleTheme() call
- Add handleModalKey case for modalThemeSelect (Up/Down/Enter/Esc)
- Add applyThemePreview() and finalizeTheme() helper methods
- Add renderThemeSelectModal() with aligned theme names + swatches
- Update renderModal() dispatch and widen modal for theme selector
- Update help text: 't' now shows 'select theme'
- Add Mirror pane keybinding p (for 'Pane'), SSH restored on s
- Add session-scoped cursor memory per directory
- Fix cursor memory bug: DisplayName() adds trailing / for directories
- Fix remote mirror: use active.Path instead of mount.RemotePath
- Remove F-key/Mouse/b/c entries from F1 help dialog
- Remove Mirror from ShortHelp footer (F-keys only)
- Add missing letter-key bindings to help: p, s, a, n, x
Add rich preview support for three new file categories by leveraging
external CLI tools with graceful fallback when tools are missing.
- PDF: text extraction via pdftotext, page count via pdfinfo
- Audio: metadata via ffprobe (duration, bitrate, codec, sample rate, channels)
- Video: metadata via ffprobe (duration, bitrate, video/audio codec, resolution)
- New PreviewKind constants: PDF, Audio, Video
- New Metadata fields for extended preview data
- New extension maps and Category() entries for pdf/audio/video
- Icons: PDF (), audio (), video () in preview header
Closes#5
Pressing / opens a filter bar at the bottom of the screen. As the user
types, the active pane's entries are filtered in real-time using
case-insensitive substring matching. The .. entry is always preserved.
Key bindings:
/ - open filter input (re-opens with previous query if active)
Esc - clear filter and restore full list
Enter - commit filter (keeps filtering active, closes input bar)
Up/Down - navigate the filtered list while typing
PgUp/Dn - scroll the filtered list
Filter is automatically cleared when navigating to a different directory
(Enter on a folder, Backspace to parent, opening an archive).
Modified files:
- internal/ui/keymap.go: added Filter key binding (/)
- internal/ui/model.go: filterMode, filterQuery, filterInput fields;
filteredPane() helper for View rendering; filter handling in Update();
renderFilterBar() for the bottom bar UI; clearFilter() helper;
adjustCursorForFilter() to keep cursor in bounds
