It should be great to have a button on the app to make an automatic 360° at a choosen speed... This button could replace the landing one which is useless (the landings are so hard when you use this feature)

+1 !!!!!!!!

And a button to take a selfie, and one to follow a line allowing you to control the camera while it flies. Oh wait, thats a 3DR solo ;-)

In all seriousness, the 360 while either taking a movie or stopping at intervals to take a still would be great. But I fear like the selfie and the cable DJI will want someone else to write it. Here is hoping though!
