Hello,
many thanks for the fantastic GSX addition v2!
One thing I would think would improve the "reality" a bit is, that crew boarding could be initiated separately.
So, if you look at the GSX menu, I think about the following:
1) Deboarding
2) Boarding Crew
3) Catering
4) Refueling
5) Loading Cargo
6) Loading Pax
7) Pushback
and so on …
many thanks for your hard work!
