Thank you! By the keys, do you mean the toggle switches that flip left-to-right? If so, I agree that they are pretty unintuitive; I want to experiment with adding a custom mouse cursor, that I hope will better indicate how to actually interact with them (as well as every other interactable object). Please let me know if you were referring to something else, though!
Also, we are going to experiment with adding a glowing effect to planes that are currently being controlled!
