Having TapFly would make a nice addition to be able to focus on camera controls while automatically flying slowly in a straight line.
Since the Mini has no Obstacle Avoidance I guess it should be used only in open areas and at slow speed.

Not many new features were added to Spark after release.
They need some space between the 'cheaper' model and the more expensive ones.

Nice suggestion!
