Perfect! I've created a comprehensive `.gitignore` file for your Blender extension project. This will exclude:
- **Blender files** (`.blend`, `.blend1`, `.blend2`)
- **Python cache** (`__pycache__/`, `.pyc` files)
- **Development environments** (virtual environments, IDE files)
- **OS generated files** (`.DS_Store`, `Thumbs.db`)
- **Temporary and log files**
Your Dynamic Link Manager extension is now ready with:
- ✅ `blender_manifest.toml` - Proper manifest format
- ✅ `__init__.py` - Main addon file
- ✅ `operators.py` - Core functionality
- ✅ `ui.py` - User interface
- ✅ `README.md` - Documentation
- ✅ `LICENSE` - GPL-2.0 license
- ✅ `.gitignore` - Version control exclusions
- ✅ `assets/` and `icons/` directories
The extension is ready to be installed in Blender 4.5.0+ and should appear in the 3D View sidebar under "Dynamic Link Manager"!
