Here is a thought for developers. When using the loiter flight mode it is possible to control the loiter altitude with the elevator stick (if FLIGHT_OPTIONS bit 12 and STICK_MIXING is enabled). Would it not also be great if the same settings also allowed loiter diameter to be controlled using either the aileron or rudder stick?
Currently the flight path can be nudged with aileron input, but when released it goes back to the same path as before. I think it could be more useful if the diameter instead would be nudged inwards or outwards.
