It's a very nice Study-level Add-on.
However, I think it needs some improvements:
1/ A remote tablet capability for the MCDU (like it is with the FBW A320 Neo), as preparing a flight in VR, with the mouse, is a pain in the... neck. :-)
2/ Differently shaped arrows for :
- rotating the (Heading/ Altitude/Speed/ Vertical speed) A/P knobs
- pushing/pulling the related knob.
At the moment we only have 'up'/'down' arrows for both functions, which is very confusing, especially in VR.
I would suggest circular arrows for increasing/decreasing the value and up/down arrows to pushing/puling the related A/P button.
Sorry for my english, which is not my native language.
