Yes first of all Video.
But also to fly Transport Missions it would be nice. Actually we are going to have a Demo (currently on AC) which really makes a nice Mission Flight (for the eye) as would a FW do. In contrast when flying Missions with PX4 it sometimes looks a bit awkward when it comes to a full stop just to bank in another direction right afterwards. Technically there is no big deal with this behavior (except that PID Tuning is more important, than when flying smooth curves).
