. . . and if not, isn't that lousy?
It appears the answer is no, but I just see the issue alluded to in other contexts.
To me it's a big deal and I think using the mouse freelook is a pain. You can map quickviews to the hat (POV arrows) and even map custom views to the hat/POV (apparently only for one airplane at a time), which helps but it's not as good. Why not go the extra step and just do freelook (the function formerly known as "panning") with a joystick hat? This has been supported in about every flightsim I can remember.
If it matters, I use a CH Products Flightstick Pro. I don't think this is brand or model specific.
