I think it'd be very nice if you were able to move and resize in-game windows such as the GPS overlay and the AV video feed - As is the AV video feed is very small resulting resulting in you having to either zooming all the way in to see details or zooming all the way out and losing the ability to tell rabbit and enemy apart. It's also covering 80% of the GPS overlay (although I assume that's a bug and it's meant to take up 100%), so being able to move it, so you can see both at the same time, would be neat.
As for the GPS it'd be nice to see larger areas - Either by increasing the size of the GPS window or having the option to zoom in/out.
