One concern about the bay-selection feature would be backwards compatability. There are several ships in both FS1 and FS2, that have more than 1 figherbay subsystem. Obviously, you'd want to preserve the original missions rather than have arriving or departing fighters, forced to use one bay or another. Therefore, I suggest that (assuming that its selectable via a drop-down tab in the arrival/departure cues) there be an option of " < default > ", which, if selected, would cause the selected ship or wing, to use the existing method of the code deciding which paths the ships should follow. It would probably require that any ships that designers want to be able to take advantage of this feature, be configured so that the bay paths are attatched in the path data, to the fighterbay subsystem, rather than to the hull submodel.
