* Quick access via context menu (right-click tab)
- Multiple match types for saved rules:

- Contains: Match URLs with keywords (e.g., watch?v=)
- Exact: Match specific URLs
- Regex: Advanced pattern matching
- Customizable theme: Dark, light, or auto (follow system)
- Session history: Track your recent volume adjustments
