I looked at your to-do wiki and did not find it there, so I hope I put the request in the right place.
I hereby request a hotkey for using headgear. I miss it dearly.
Also, would it be possible to disable the "right click destroys building" function? It is a nice touch you tried to make the interaction faster, but I'm actually not destroying so many of my own buildings that I thought "Oh, if there was only a faster way".
In fact, I once missclicked and destroyed my hospital (yes, even if there was a message "DO YOU REALLY WANT TO DESTROY THIS BUILDING?" I simply missclicked, and man it happens so fast...).
Another request would be to send aircraft out on patrol without an objective (e.g. a mission). This one is totally important, though, but it occurred to me it would be nice to do soe patroling.
