Hello there,
FMS is great, but there are some ways how to improve it:
1) It is possible to add feature of switching between two models (like Harrier flying in mode 'helicopter' and in mode 'airplane', or 'landing/take off' and 'flying' versions of many other models) in the game-time?
2) Can you add some endless(self repeating) scenery to FMS? It is terrible to watch a plane crash in the white empty space.
3) Can there be some water-recognizing(special water map file for each scenery)? It's weird to see Boeing-747 landing in the middle of the lake(but some planes would be able to land on the water, of course).
4) Multiplayer. I know this is little bit difficult, but it would be a great improvement.
5) Environment sounds - wind, water, birds...
6) And one more thing: when I load model from other directory than FMS\Model, it is OK, but next time I try to open a model, I am placed again in FMS\Model and have to browse some time.
