M8: Pre-compile regex once before rename preview loop instead of
recompiling per file. Adds apply_simple_compiled() to RenameConfig.
M9: Cache font data in watermark module using OnceLock (default font)
and Mutex<HashMap> (named fonts) to avoid repeated filesystem walks
during preview updates.
M12: Add 150ms debounce to watermark opacity, rotation, margin, and
scale sliders to avoid spawning preview threads on every pixel of
slider movement.
M13: Add 150ms debounce to compress per-format quality sliders (JPEG,
PNG, WebP, AVIF) for the same reason.
M14: Move thumbnail loading to background threads instead of blocking
the GTK main loop. Each thumbnail is decoded via image crate in a
spawned thread and delivered to the main thread via channel polling.
CLI: add UTC suffix to timestamps, validate image extensions on
single-file input, canonicalize watch paths for reliable matching,
derive counter_enabled from template presence, warn when undo count
exceeds available batches.
Core: apply space/special-char transforms in template rename path,
warn on metadata preservation for unsupported formats, derive AVIF
speed from compress preset quality level.
GTK: use buffer size for apples-to-apples compress preview comparison,
shorten approximate format labels, cache file sizes to avoid repeated
syscalls on checkbox toggle, add batch-update guard to prevent O(n^2)
in select/deselect all, use widget names for reliable progress/log
lookup, add unique suffix for duplicate download filenames.
CLI now stores Unix seconds (matching GTK) so age-based history
pruning works correctly. Human-readable formatting applied only
at display time in cmd_history and cmd_undo.
- cleanup_placeholder now removes 1-byte marker files on error (regression)
- {width}/{height} template vars replaced with "0" when dimensions unavailable
- Text watermark width multiplier 0.6->1.0 to prevent CJK/wide char clipping
- cmd_undo preserves history entries when trash operations fail
- cmd_watch_remove exits on write failure instead of silent discard
- PNG chunk parsing overflow protection with checked arithmetic
- Font directory traversal bounded with global result limit
- find_unique_path TOCTOU race fixed with create_new + marker byte
- Watch mode "processed" dir exclusion narrowed to prevent false skips
- Metadata copy now checks format support before little_exif calls
- Clipboard temp files cleaned up on app exit
- Atomic writes for file manager integration scripts
- BMP format support added to encoder and convert step
- Regex DoS protection with DFA size limit
- Watermark NaN/negative scale guard
- Selective EXIF stripping for privacy/custom metadata modes
- CLI watch mode: file stability checks, per-file history saves

- Saturation/trim/padding overflow guards in adjustments
Critical fixes:
- Prevent path traversal via rename templates (sanitize_filename)

- Add BatchResult.output_files for accurate undo tracking
- Implement auto_orient_from_exif() that reads EXIF Orientation tag
and applies the correct rotation/flip for all 8 EXIF orientations

- When lock is active, changing width auto-calculates height from
the first loaded image's aspect ratio, and vice versa
- Uses recursive update guard (Cell<bool>) to prevent infinite loops
- Add rotate_watermark_image() using imageproc rotate_about_center
for 45/-45 degree rotations and image::rotate90 for 90 degrees

transparent buffer for rotation before compositing
- Apply rotation to single text, tiled text, single image, and
tiled image watermark modes
- Fix tiled image watermark to use actual overlay dimensions
(which change after rotation) instead of pre-rotation values
- Move watermark step after compress in processing pipeline to match
design doc order (resize, adjustments, convert, compress, metadata,
watermark, rename)

modes using little_exif tag filtering (GPS, camera, software,
timestamps, copyright categories)
- Add case conversion support to rename (none/lower/upper/title)
- Add regex find-and-replace on original filenames
- Wire case and regex controls in rename step UI to JobConfig
- Add regex crate dependency to pixstrip-core
Support {date}, {exif_date}, {camera}, and {original_ext} in rename
templates. Reads DateTimeOriginal and Model from EXIF metadata via
little_exif when these variables are used in templates.
Active watch folders from settings are now monitored using the notify
crate. When new images appear, they are automatically processed using
the folder's linked preset. Toast notifications inform the user.
Each ExpanderRow now remembers its expanded state between sessions
using a per-section key stored in SessionState. Replaces the global
detailed_mode toggle with granular per-section persistence.
Wire tiled, margin, and scale UI controls to JobConfig and pass
through to WatermarkConfig. Add tiled text and image watermark
implementations that repeat across the full image. Add font family
filesystem search for named fonts. Add WatermarkRotation enum.
Toggle button in the header bar reveals a bottom panel showing active
watch folders with their linked presets and watching status. The add
button opens Settings for full watch folder configuration.
Users can now choose between subfolder-next-to-originals or a fixed
output folder in Settings > General. The fixed path is selectable via
a folder picker dialog and persisted across sessions.
PNG files now embed pHYs chunk for DPI when output_dpi is set, matching
the existing JPEG DPI support. Also fixed FontDialogButton signal handler
to properly unwrap the Option<FontDescription>.
Font picker using GTK FontDialog/FontDialogButton lets users choose
any installed system font for text watermarks. The selected font family
is passed through the processing pipeline and used to find the matching
font file on disk.
