On the first request: I think the both of you are talking about two different things.
Ferdinando, When GSX2 was released the Crew bus always came first, and always came to the aircraft last, to complete Boarding and De-boarding. People requested that Boarding and De-boarding be for passengers only, as you, as Crew, were already on board, having completed pre-flight checks and were now requesting boarding of passengers.
The FSDreamTeam obliged and now, in the Set-up menu, there is a tick box to prevent the animation of the Crew arrival, and later their departure. That is the option I use as I notionally stay on board during a turn around.
Correct me if I am wrong, I believe what Ferdinando is asking if he can have the Crew arrival sequence separate from the Passengers?
