Then GSX is not for everyone, but you promote that it's for everyone.
We don't promote it to be for "everyone", we always said it works at all default airports, not with each and every 3rd party airplane, from day one.
I understand the thing with the correct door positions, but I hate when I've to see a stair at an Overland Airbus A330-200 which misses the correct door exit hugely.
Sure enough, but with hundreds of payware/freeware airplane available, you can't expect to have them supported all from day one, and nobody promised this. They will come, in time.
If you would add those planes, then you have added a lot of planes as there're a lot of plane in one package, but with adding for instance just a Captain's Sim ...., you just added one plane.
Apart for the fact that, we also added the JF757, and that the Captain Sim 727 is really two airplanes (since the -100 and -200 have different sizes, the *are* effectively two airplanes) and they are much more complex to support, rather than just adding door coordinates, but how many new airplanes PER DAY should we add, to make you happy ?
I guess any number will probably never satisfy everybody, but it's a brand new software, and it's being DESIGNED to be constantly updated, so everything related to interaction with 3rd party addons will eventually arrive.
