I am slowly transitioning into MSFS so when GSX is finished for that platform maybe the same editing capabilities will be available there.
GSX in MSFS will have even better editing capabilities:
- Passenger Waypoints will be in 3D, so they could climb staircases, raising platforms, etc.
- It will be possible to add Passenger waypoints on gates with Jetways as well, for example to let debearding passengers continue their walk well inside the terminal.
- It will be possible to create walking paths not related to the actual boarding/deboarding procedure, but as infinite loops of people walking inside terminals, like the "Airport Walkers" currently only seen on P3D versions of KORD V2 and Basel.
We are planning to port back those features to P3D as well, but after the initial release for MSFS.
