Maybe surface terrain (when wanting to land on object) could be a advanced-graphics option for those who have beefed up computers.
Also, bring back some of the default-maps I don't get why Io (when you open the Solar System with Major Moons simulation) by default has an ocean visible with a blue atmosphere?
