I looked through the mega thread and didn't see the ideas I had. I would love it if you could select multiple blocks and change their parameter tuning together. It would make creating go a lot faster for the big machines. The other idea I had was camera related. First, I would love a camera setting that stayed facing forward so you don't have to keep turning the camera for airplanes and helicopters. And if you did turn the camera once you let go it would smoothly go back to facing the front.
