I would like to have a proving ground. Something with a steep hill, so sound designers could test tanks at high speeds, and then have the different surface types all arranged down a straight and also curved path for sound testing. I have until the end of this week and then I will be busy for another eleven weeks, so no hurry or anything (this for terrain builders). Obviously, I don't want to have to learn how to make terrain. Obviously, this would help other sound designers, also.
I wish there were a door event for the M3, and Sd. Kfz. 251. No, it adds nothing for the game, except you will be able to tell the door is open, or closed, without having to actually look.
