I was thinking that there should be a key binding menu. It would be up in the corner of the screen, and it would allow you to see what all your key binds are and what they are connected to. The most important feature would be that they would allow you to change multiple key bindings at once. Right now, if you want to change a key within a complicated logic circuit, you have to sift through all the logic blocks to find all the places that the key exists. This can create a lot of glitches. Also, if a creation has a massive amount of thrusters, you have to manually change every single thruster, or delete them all and start again.
