Add action button to camera view

It should be possible to have an action button on the screen when viewing a camera. Leaving the camera view to press an action button then returning to the camera view is not good enough if you want to see if its save to, for example close a garage door, and be able to quickly stop it should something unexpected come into view. It should be possible to close a garage door AND watch the garage door before, during and to complete closure without interrupting the viewing. Yes the garage door does have its own safety features but being able to watch it would be so much better.

This applies to any camera view of any camera type.
