cd <unity-project-root> && node .unity-websocket/uw prefs clear

# Force clear all EditorPrefs

## EditorPrefs Storage Location

EditorPrefs are stored per-Unity-Editor (not per-project):

- **Windows**: `HKEY_CURRENT_USER\Software\Unity\UnityEditor\CompanyName\ProductName`
- **macOS**: `~/Library/Preferences/com.CompanyName.ProductName.plist`
- **Linux**: `~/.config/unity3d/CompanyName/ProductName/prefs`

**Note**: CompanyName and ProductName are from your Unity Project Settings.
