Hi,
this is a topic that needs to be addressed in a bit bigger/general way to Umberto.
GSX is a very nice addon and many of us can't imagine flightsimming without anymore.
But the way GSX is still working seems and looks quiet outdated. If you're on an airport and see how real crew's are handeling an airplane once its arrived and prepared back ready for departure, you will see that many things happens at the same time and therefore not synchrone.
I would love if you could add more animations to the ground people that it doesnt look like mirrored and every time the same, that stairs didn't move without any small tug moving it away, pushback truck isn't on your gate once you turn into the gate after arrival, but it arrives once you ask for pushback/departure. Or you can choose if a jetway is available if you want to use the jetway or stairs (for RYR ops for example).
We still need some more services to be done like cabin cleaning, water car etc.
Car modelled needs updates, the crew bus is since its implementation odd. I never saw anything near that crew bus on any german airport yet. Therefore Lufthansa uses complete busses in their design as crew busses in Frankfurt for example.
It is time (with MSFS especially) to get GSX more flexible and operations more realistic and more things at the same time done.

Timm
