The ability to program the Rockets that you make. Yes. I'll possibly add that into "Five Rockets at the VAB". It won't be complex obviously. It's just "When [stage] runs out of fuel then", maybe even "Planned orbital parameters [Apoapsis, Periapsis, Inclination]" and "If Apoapsis over x then". Obviously this'll be like block based, or something like that, Just like Scratch.
