Tips

• Drag the bubble anywhere on screen if it's in the way
• The notification bar shows "Overlay active" while running
• To stop: pull down notification → tap Stop, or go back to the app and tap Stop Overlay
• If the circle is slightly off, use "Board size" in settings to fix it (pick your actual board size instead of Auto)
