Since they are adding interstellar systems, now is a better time than ever to add an easy way to make custom celestials. Basically, in the main menu there is an option titled edit universes (can't call it solar system anymore!) Clicking this button would take you to a screen where you could choose a universe (for lack of a better word, maybe star cluster instead, just all the celestials in the game) and edit individual celestials. You can also clone a universe of create a new one, place a celestial, edit orbit and celestial parameters, all the stuff you would expect. But it would also have other things, such as auto calculating radius based on density and mass, and creating realistic orbits just like it would for a ship. As well as tools to edit a surface, such as being able to overlay the color map over the height map and edit each side by side. What this would mean is that people with good ideas but no coding knowledge could realize there ideas. And more interesting ideas could come out as a consequence, plus new categories, such as sillier planet mods could be created.
