This suggestion is about adding the ability to rotators to make them gradual. Meaning, their speed being adjustable based on input. That way it would be easier to make electric engines for example. Where you can adjust the rotation speed based on the throttle input.

It would also be nice if all rotators had a "zeroondeactivation" boolean function. Meaning, if you were to "idle" or "deactivate" the rotator, it won't start rotating in the opposite direction till it's back on it's starting position.
