- Improve Code Quality: Maintain cleaner codebase
- Save Time: Eliminate manual reference searches
Features
- Inline Reference Counts: Display usage counts next to definitions
- Unused Symbols View: Dedicated sidebar for zero-reference symbols
- Multi-language Support: Python, JavaScript, TypeScript
- Performance Optimized: Auto-excludes node_modules/build folders
- Real-time Updates: Config changes apply immediately
- Smart Import Handling: Excludes imports by default (configurable)
