I think that the Devs should add bomb bays to the game, so that we don't have to use too many parts to make a simple bomb bay. They should also create more cockpits for jets, so they look more realistic. There should also be new guns like AAA guns, tank guns, and the ability to change the caliber size of a gun without xml modding. Last of all, I think there should be a new mission for all platforms (iOS, android, windows, OS X, etc.) that places you in a full-on ww2 naval battle, having you take off of an aircraft carrier to take out enemy planes and ships (subs, destroyers, cruisers, battleships, carriers, etc.).
