Hey! First of all, I'm loving the mod.
Second, I have a few ideas for you. I'm not going to be offended, but I do see that you are planning to have the 2019 version of Starship. If/when you do, I think it would be nice if the stock KSP texture switching was used to chose between carbon fibre and steel. In addition, it would be cool to have a built-in heatshield that drains LiquidFuel to protect from heat.
The other thing I think is missing is the sattelite deployer/cargo Starship with the big swinging front door. That would be really fun to have.
Other than that, IVAs for the Starship would be nice.
I don't mean to sound like I'm complaining; I love your mod and have used it for quite some time (with little success due to my mediocre piloting skills, though I did land on Duna!).
Another idea would be to modify the Rodan (Crew Dragon) command pod so that it doesn't have the landing legs. SpaceX is just doing a parachute landing at this point if I remember correctly.
Other than that, I honestly can't think of too many improvements! Your mod is amazing as it is!
