Is there some sort of mod that splits up KSP into 2 windows, where one window is for the controls, and the other shows the display. A bit like Nintendo xDS systems, where the game is displayed on the top screen, and the bottom shows the technical details. I think this would also help for cinematic productions so you don't have the UI cluttering up the screen. Although I guess you could set the recording program to record only the part that focuses on the rocket instead of the UI. But this would be a cool idea.
