The first load of a file decodes the whole audio track in a background
thread; nice'ing it (os.nice(15)) reduces disk/CPU contention with mpv
during the initial open. Result is cached, so subsequent loads are fast.

Missing files are kept in the list instead of being silently dropped on load,
and styled distinctly with a tooltip. add_files gains allow_missing; tab
restore keeps missing entries so they're visible.

Replace the per-folder submenu/buttons with one batch action: "Disable all"
moves every enabled subcategory (excluding the main folder and already-disabled
ones) to _disabled in one click; "Enable all" restores them. Available in both
the playlist right-click menu and the Sub button menu.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Folder-wide disable/enable is now reachable right next to the per-video
"Disable in" submenu, listing every subcategory in the profile (not just
ones tied to the loaded video). Backed by profile-wide subcategory counts
pushed to the playlist in _refresh_playlist_checks.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Previously the Sub menu only showed folders from the current video's markers
plus configured subprofiles, so subcategories without clips on the loaded
video (or without a matching subprofile) never appeared. Now it also includes
every subcategory that has clips anywhere in the profile (active or disabled).
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Sub menu now has per-folder "Disable all" / "Enable all" buttons with live counts
- relocate_video_clips accepts filename=None to move every video's clips in a folder
- get_all_folder_counts returns profile-wide per-folder counts (incl _disabled)
- Disable-all confirms before moving; both refresh markers + playlist counts

- Wrap the playlist in a QTabWidget; each tab is its own file list
- "+" corner button adds tabs; double-click a tab to rename inline; tabs are closable (last tab protected) and movable
- self._playlist now resolves to the active tab's PlaylistWidget
- Persist tabs (label + files + separators) per profile as JSON; falls back to legacy session_files/separators on first load
- Filter box and playlist filters apply to the active tab; tab switches reapply filters and refresh marks
- Profile switch/duplicate/delete now save/load/copy/remove per-profile tab state

Subprofile/subfolder exports now appear as colored markers (yellow,

mpv's "absolute" seek lands on the nearest keyframe before the target,

Revert span opacity back to 35 (was fine). The actual issue was the
play position line disappearing when scrolled out of the zoomed view.
Now set_play_position auto-pans the view window to keep the playback

Add clip duration spinner (2–30s, default 8s) replacing all hardcoded
8.0 references. Store clip_duration in DB for accurate re-export span
calculations. Add x2/x4 playback speed toggle buttons. On Windows, mpv

Re-export dialog now offers two modes: keep section length (adjust clip
count) or keep clip count (adjust section length). Files shared with
other profiles are preserved during re-export. Vid folder is resolved
before DB deletions to reuse existing folders. Add delete profile option
with confirmation dialog. Profile duplication now copies all tables
including processed exports.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Re-export button (next to Spread spinner) re-exports all manual clips
for the current file into the current folder with the new spread value.
Old files are deleted from their original locations first.
Duplicate profile option in the profile dropdown copies scan_results,
hard_negatives, and hidden_files to a new profile name (exports are not
copied since they reference file paths tied to the source profile).
Also widened get_profiles() to include profiles that only have
scan_results or hard_negatives, not just exports.

When a scan result row is clicked, if the active region falls outside
the current zoomed view the view centers on the region (and widens if
the region is larger than the current span).

Ctrl+scroll zooms the timeline view around the mouse. Middle-mouse drag
pans when zoomed. Scrolling all the way out clamps back to full view.
While dragging a scan region edge with Shift, the view auto-pans when
the mouse approaches the widget border so you can extend a region past
the visible range.
All paint and hit-test paths now route through _time_to_x / _pos_to_time
helpers backed by a _view_start / _view_span window, so existing
interactions (seek, marker click, edge resize, keyframe context menu)
all adapt naturally to the zoom level.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Add "Merge N rows" context-menu option that combines selected scan rows
into one (min start, max end, max score), with full undo support.
Ctrl+Z is now an application-wide shortcut so it works regardless of
which widget has focus. Negatives undo now respects the exported-green
row color instead of reverting to default.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
- Scan panel button now reads "Export Selected (N)" while rows are
selected, mirroring the clip-count estimate used for full exports.
Selection changes fire an explicit signal so the label refreshes.
- Export markers remain visible on the timeline in scan/review mode.

- Right-click on exported (green) rows shows "Delete export" to wipe
associated clip files, annotations, DB rows and empty vid folders;
scan panel, markers and playlist badge refresh afterwards.
- Exporting with rows selected in the scan panel now runs a partial
export: prior scan exports are preserved, and the area index for new
clip filenames is offset past existing a-suffixes in the vid folder
to avoid collisions.

Two bugs caused vid number collisions (multiple files sharing a vid_NNN):
1. "First gap" assignment (n=1; while vid_n in existing: n++) would

2. LIMIT 1 without ORDER BY returned arbitrary rows when a file had

Root cause of poor discrimination: MFCC[0] (energy) dominated the
feature vector, making cosine similarity see all audio as similar.
Changes:
- Skip MFCC[0], use 12 coefficients instead of 20
- Add delta MFCCs for temporal dynamics
- Add 7-band spectral contrast for tonal vs noise quality
- Switch from cosine similarity to euclidean-distance-based score
- Pre-compute STFT once for whole file (10-20x faster)
- Vectorized sliding window via cumulative sums (no Python loop)
- Lower sample rate 22050→16000 Hz (faster, no quality loss)
- 62-dim feature vector (was 40-dim mean+std of raw MFCCs)
- Default threshold 0.05 (new similarity scale)
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Mean-only vectors were too similar across different audio segments,
causing everything to match even at threshold 0.99. Adding std
