Manage decos
- Select Import GIF (bottom-left) to add a new animated overlay.
- Press Wear / Take Off (bottom-right) to toggle a deco’s visibility without removing it.
- Adjust position, size, direction, playback speed, and other behaviour from the property list.
- Unlock a deco to drag it freely; lock it once positioned so the window beneath remains clickable.
