CHANGELOG:
Version 2.2 (2025-09-16)
- FIXED: The script no longer clicks on comment previews in the main feed.
- USABILITY: Added a `setInterval` poller to run the `expandCommentReplies` function periodically.
- This ensures that comments visible on initial load are expanded proactively, without needing to scroll first.
- It also acts as a safety net to catch any reply buttons missed by the MutationObserver, providing a much more seamless and responsive experience.
Version 2.1 (2025-01-06)
- NEW: Added automatic comment reply expansion feature
- NEW: Configuration option to enable/disable reply expansion
- NEW: Smart scroll position preservation during reply expansion
- NEW: Viewport-aware processing (only expands visible replies)
- IMPROVED: Added debounced scroll handling for better performance
- IMPROVED: Better detection of reply buttons across multiple languages
Version 2.0 (2025-01-06)
- FIXED: Major bug where "All Comments" would incorrectly select "Newest" due to partial text matching
- ADDED: Smart text matching that prioritizes exact matches at the beginning of menu items
- ADDED: Comprehensive debug logging system with DEBUG flag
- ADDED: Better handling of Facebook's combined menu text (title + description)
- IMPROVED: Menu item detection logic with multiple fallback strategies
- IMPROVED: More robust parameter mappings for Facebook's GraphQL API
- IMPROVED: Added support for more API parameters (view_option, sort_by, isInitialFetch)
Version 1.2 (2024-12-XX)
- Added support for multiple languages
- Improved URL interception for XMLHttpRequest and fetch
- Added POST body modification for GraphQL requests
Version 1.1 (2024-XX-XX)
- Added parameter mappings for comment sorting
- Fixed menu item selection logic
Version 1.0 (2024-XX-XX)
- Initial release
- Basic comment sorting functionality
