It would be really great if X-Plane 11 allowed users to directly bind joystick axis to "head look", e.g look up/down and look left/right.
That would allow pilots to use EDTracker without the need to run opentrack as a 'go between'. Opentrack is free and uses virtually zero resources so it's not a showstopper but seems like a 'quick win' to allow direct binding.

X-Plane 10 allowed directing binding in this way
