I'm pretty new, so some of these features may be available and I haven't found them but here goes:
I'd like to see the planes listed with features such as number of channels, level of difficulty, type (bi-plane, aerobatic, heli, trainer, etc)
I'd like a "flight-line" feature, where you are buzzed/penalized if you cross the flight line, like the rules prohibit in real life.
I'd like more info for true beginners that go over the real basics of flying, turning, landing, keeping orientation, etc. The training videos are great for advanged maneuvers, but not so much for beginners. I'd like to see training videos on simple things like turning, keeping level, how high to fly, how to line up for landing, how to land.
Would be fun to have some games and even a cartoon mode.
