I would like to see a feature in FGRun to allow the 3D Model view to accept user inputs (joystick/mouse/keyboard) to test control movements, rudder, jets, etc... of the craft without having to run FG itself. For instance one could test a new landing gear script without having to load all the scenery. A development test mode in a sense. Even if it is only available with just a mouse or keyboard it would be nice.
FGRun already has a viewer and reads the xml's to place the parts of the various craft. How hard/easy would it be to add this???
Is it also possible to branch off FGRun and modify it up to include an xml/nasal editor, on the side of the viewer, to create and test xml/nasal with a live 3D preview? just as a development tool...
