Same actions for sensors on entering and leaving & Have options like expand and retract for rotors
Sensors can trigger an action when entering the sensor field and another one when leaving it.
Let's say, I want a sensor to open und close a rotor based door. Because rotors do not have separate options for retracting and expanding like pistons - a problem by itself, if you ask ask me - I need to use reverse on both actions of the sensor but it won't let me do it. I know there are workarounds, but I don't see the point in making it complicated.
