Agreed. I was going to ask this very question myself.
Edit: This would help us make the simulated quad behave more like our real life counterparts.
Came here to request the same thing, with the GUI being hidden. The elements aren't really distracting since they are static, but they generally make for a lower quality feel in my opinion. I would even consider making them part of a menu when you press escape rather than having them on screen at all times. These are just usual conventions in design. It's rather peculiar having them visible at all times.
