I would say that the ONLY thing I wish the DJI software would allow for, which the Ardu has, is the nose-in-circle-mode. I don't see it would take more than a few hours of coding by the sweat shop.... The parameters of the circle, namely, the radius, could be set in the assistant software and the initiation of the maneuver could be as simple as adding another mode to the mode switch option. So like GPS, attitude and Circle/Attitude/Manual. Even the ground station doesn't do it, which is a real let down.
