Changes: 1. Categorize HARDCODED_IGNORE_PATTERNS into 4 distinct lists: - QUALITY_PATTERNS: Quality tags ([4K], HD, (SD), etc.) - REGIONAL_PATTERNS: Regional indicators (East) - GEOGRAPHIC_PATTERNS: Geographic prefixes (US:, USA:) - MISC_PATTERNS: Miscellaneous patterns ((CX), (Backup), single-letter tags) 2. Update normalize_name function signature: - Remove remove_quality_tags parameter - Add ignore_quality, ignore_regional, ignore_geographic, ignore_misc (all default to True) - Maintains backward compatibility with default True values 3. Implement dynamic pattern application: - Build patterns_to_apply list based on category flags - Apply only selected pattern categories 4. Improve user_ignored_tags handling: - Tags with brackets/parentheses: literal match - Simple word tags: use word boundaries (\b) to avoid partial matches - Fixes issue where "East" tag would incorrectly match "east" in "Feast" 5. Update version to 25.313.1157 (Julian date: Nov 9, 2025 11:57 AM) This refactoring enables future UI controls for granular pattern filtering while maintaining full backward compatibility.
