What it does
Pauses shaking the moment any app starts using the camera; resumes when the camera is released.
How it works
Shake It On enumerates video capture devices via AVFoundation and checks `isInUseByAnotherApplication`. Any camera in use → pause.
Where to find it
Settings → Paused When → Camera is in use.
When to use it
Always. There's no good reason to jiggle the cursor during a Zoom call.
