- Easily disable addresses if they get compromised

| **Enable/Disable** | Toggle masks on or off without deleting them |
| **Edit Details** | Update description, domain, and URL associations |
| **Quick Copy** | One-tap copy to clipboard |
| **Delete** | Remove masks you no longer need |
| **Search & Filter** | Find specific masks instantly |
| **Material You** | Dynamic theming that adapts to your wallpaper |
