I downloaded the demo about an hour or so ago (couldn't by it because my CC has not been working at all lately) and after trying it with a friend, we came up with a couple of suggestions:
1- Could you add a menu or some interface where you could select how long the services would last? For example, for me, the boarding, deboarding, loading and unloading are too fast. Maybe we could choose whether we want it to last 5 minutes or 10 minutes, depending on the size of the plane. Say, if it's a heavy, boarding will last 20 minutes. If it's a medium size airplane, it would last 10 minutes. And so on.
2- I noticed the refueling truck works pretty much like the default FSX one. It comes from somewhere, stops by the plane, opens FSX's load manager, and when you close it, it simply goes away. Coudn't you also put an option in that menu I mentioned above to force the fuel truck to stay there for 5 minutes, just to pretend it's fuelling the plane?
3- Can you add an option for us to choose whether or not we want people walking from the stairs to the bus in case we've parked in a spot with no jetway? It would be nice to have a couple of folks walking outside while boarding or deboarding. I understand having 100 people walking around the scenery would have a massive impact in framerates, but adding a few folks wouldn't be bad really...
I think that's it for now. I have to say, though, that I really enjoyed the product demo. It's working perfectly. I wonder why any other developer (Aerosoft aside) made this kind of product before. I don't see myself flying airliners without it anymore. You made a great job with it. The marshallers doesn't have that robotic motion. Everything works fine, in perfect harmony. Can't wait for the eventual expansion packs you may release for it.
