The altitude Ias and radio channel displays can be moved from the GUI options tab in preferences. The key mapping works...ish. Seems you have to keep the "cursor ball" very still? Its doable, but takes some effort. I have had no issues with changing key mappings, other than the difficulty keeping the ball on the "OK,Cancel, ect tabs). The key mapping popup might even show up directly behind the "clip board". I have had to move clipboard to other side to reveal the key mapping window. Yes, the Guns both Ship and Field are a bit wonky as compared to non VR. The clipboard
In your face is an understatement for a fact. Cant help with that one
Sort of wish the mouse was in control of the "Cursor ball" instead of the head position. It might, I dont know? Havent found how to do it if it can be done
