I agree with all of the above.
I have the same issues. On the Pilots position I used the flywithlua script Log pilot head position to set all seats VR position.
I have experienced all of the others as well. On the SR22 you have to prime it in 2d and select the fuel tanks too, since the VR button won't work. I really dislike unnatural motions in VR, it breaks the immersion. If i load, reload too many times the simulator crashes.
