...for repainting. I would (as well as anyone who has ever tried to repaint one of the more complex aircraft out there!) like a utility that allows you to see the entire aircraft without having to start FS9, saving countless hours of testing and checking for glitches that need fixing. This would be a godsend to many of us!
Another, much more complex idea would be a free, more stable and reliable alternative to Abacus's FS Repaint. It would, ideally, have your basic image editor layout, close to MSPaint. This also makes it more feasible for freeware.
