Backlights, maybe with a toggle on and off, on left side or front perhaps?
Detents definitely
Toggle switches, the ones on the mock up look like the cheap style that snap off??
Labeling panels, it looks like you have them on there.
How far is the travel on the throttle? looks shorter than the warthog. Not that it's a criticism, just wondering.
It looks amazing though, I can't wait to see the final product!
Also +1 on the name of that seat
