Thanks for the kind words.
1. We haven't added any 3D capture modes because there isn't really a one-method-fits-all way to plan the flight and have it work out well most of the time. Good 3D models require lower flight. For now, the workaround is to manually adjust the gimbal after the aircraft heads towards the first waypoint. Adjusting it upwards about 30 degrees seems to work the best. Doing this on two consecutive mission 90 degrees to each other collects OK detail for the vertical surfaces without getting any horizon.
2. We are not planning to release an Android version. There is no way to "convert" an app and it would basically require a full redevelopment.
3. We are looking at it still. There are a couple of safety issues that are pretty hard to overcome and we are waiting on a feature from DJI before adding it.
