ADD: Freeze/Lock this/all on the Characters/Scenes/Props (with Unfreeze this/all).
I'd like to have a Lock for the Images, so I do not inadvertently bump or nudge something that needs to be in multiple scenes.
Ideally, "Freeze All" and "Freeze This" would be great, with an "Unfreeze This" and "Unfreeze All"
Lock all Props
Lock all Characters
Lock all Scenes
