Just a brain fart! While I understand there are apps available for IOS devices that enable subject tracking and the phantom 4 has this feature enabled in the GO app. Its something I would like to use on the phantom 3 within the GO app. Im guessing it may be turned on as an additional feature later in the year because at the moment its a marketing tool for the phantom 4. I saw another app has a walls feature. Brilliant idea, these things should be part of the stock app, not that I don't want to support developers but there are already a few apps, costing from £10-£22 each that have their own advantages and disadvantages but to get a good toolkit I would have to buy each app and switch between them to get the type of shot I want. For me the DJI Go app would be perfect if it included the walls and subject tracking features as well as automatic 360 panorama shooting. Maybe I'm asking too much but who knows. If you could have anything in the stock app, what would it be?
