My biggest wish, and this would be in line with what my previous favorite space sim "Celestia" had, is the ability to have add-on content that includes the asteroid belt, and all known asteroids, all known comets, and of course all artificial satellites, and their orbits.
SpaceEngine already has all this capability, except perhaps fixed orbits for spacecraft. Addons have already been made for some of these things (I myself made an asteroid addon). Adding all known objects would be nearly impossible though since there are hundreds of thousands of them, and SE probably cannot handle that many objects in one system.
