Toggle the RocketSim overlay via a button from inside the actual Simulator app

[rursache]

I think it would make a lot of sense to have a button injected (or overlay if not allowed by the sandbox) in the simulator nav bar which will toggle the RocketSim overlay

This would keep my screen clean but allow to have rocket sim running in the background

I don't use the menu bar icon and another keyboard shortcut to remember is not something i'm interested in
