I was just looking at the "EZ-GUI Ground Station" App for MultiWii and Naze32. Man, that's a slick phone app. It would be nice to have the whole GCS Suite, but the thing that would be most useful is the autonomous fight programming. To cook a flight program, in-situ and download through a USB, is top of my wishlist. Most of the other functions are more geared to bench setup.......PID tuning would be a good field tool as well
