There's lots of suggestions in this thread for more features, minor things, unnecessary things, things that can wait and that players have managed without. But if you want to make what you have as good as you can, you need to concentrate on what you have, to the exclusion of everything else. I'm guessing aero is at least party done, you have to finish it because it's too big a thing to only do half way, it'll affect too many other parts of the game so once aero is sorted, fix whatever aero broke, and it will break other stuff, changing something as fundamental as how air works isn't some magical fix for the rest of the game. Once that's done finish whatever else is mostly there, be it fairings or whatever, and for anything else on your 1.0 wishlist that isn't already mostly complete, cross it off the board and leave it for later. After that, no more work on features for 1.0, even if it's delta Vee, even if it's new contracts, even if it's new parts. No matter how much players want X or Y or Z, cross it off the board for 1.0 Once that's done you look at the bug tracker, it's got up and down votes so the players can tell you which bugs they think are important and which they think aren't, they can do this while you're fixing whatever new aero broke so it's ready when you're ready. Then just fix what you already have, no feature request, no feedback, just the bugs. Then you'll be ready for 1.0
