Great tool for videomaking, thank you very much for creating this! :) My only gripe is the roll axis being linked to yawing with non-level pitch (so basically, if you're looking up or down, the camera will always tilt/roll while turning left or right, which cannot be easily countered during smooth panning shots)
If you're still looking for feature suggestions, I'd love a way to bind either FOV (zoom) or DOF Distance to different inputs.
