Not a major issue. I was using C2 for the first time yesterday and had a hard time figuring out the difference between the objects angle and its angle of motion.

Under custom movement-angle of motion it just says "Set" instead of "Set angle of motion". You'd think it would be obvious what "Set" means if its under Angle of motion. But the description says "Sets objects current speed". So when I tried to change an object's angle of motion it was the last thing that I tried.
