Here are a few command that I think would be convienient:
1.getpadnow/trg for "C" and "V" key.(Engine thrust check. In fact this is the key for the player to control the robot unit after transformation, Allowing the unit to move more like a robot than a plane.)
2.a command that turns the gravity(stall calculation) on/off in .rse.(makes it possible to reduce to 0 speed without stalling in scenarios other than space1/2/3.)
3.playmovie command.(for MPG1/MPG2 standard 4:3 resolution videos)
