Hey @stucki!
When it comes to saving states of some components (enabled/disabled, some changed properties…) i didn’t put any automation into that. It all depends on you. In various situations you could want different approach to it
Every interaction happens instantly (one frame).
No component requires anything other than some other components from Easy interactions, so it does not care if you have one or thousand cameras 
Easy Interactions is currently available on sellfy ( https://sellfy.com/p/fNM3/ ). Epic Games also accepted it so I am waiting for it to show up on marketplace. In both places price is $24.99
