I would like to see more space plane parts, currently, to make a functioning one is very hard, let alone make it look very realistic to a space shuttle. It would also be cool to have a part that can store small ships or something, like in space shuttles and how they have the extending arm thing. maybe just make it so you can hold a probe body inside the body instead of on the side of it, because putting it on the side can ruin the flight pattern or mess with other things that need to go on as well.
