Add inner and outer asteroid belts of star systems that would serve as refueling spots for space platforms and as additional interesting obstacles for space logistics. (Like the asteroid belt mod)
; Give large planets rings as a space location without a surface (as an alternative to a moon), where the location itself contains many asteroids suitable for space platforms.
; Use an existing mod that adds new asteroids with new resources (or create new asteroids yourself) that could be mined in asteroid belts or planetary rings.
Allow some large planets to have several small moons instead of always just one.
Maybe add a convenient UI for quickly moving the map to the star systems you need instead of endless scrolling of the space map? Or at least allow zooming the space map further than in vanilla.
Make space routes connect planets only to their own barycenter and their own moons (and the same for moons — they should connect only to the planet they orbit), rather than to other objects around the barycenter.
Color-code planets based on their characteristics: hot planets get a red sprite, warm ones yellow, temperate ones green, and cool/cold ones blue and purple.
Make your mod's materials compatible with other mods — for example, zinc from Paracelsin and gold from Secretas, and so on. Or alternatively, add a setting that removes these extra materials, many of which are not used anywhere anyway.
Improve the planet content descriptions on the space map, because they are often misleading due to incorrect data. For example, almost every planet shows that it has some kind of vegetation.
Fix solar power in space — it often happens that the planets farthest from the star have the highest solar power in space, when it should be the planets closest to the star.
Improve planet generation so there are no incorrect seams between lava and water or other planetary liquids, and so on. Use a single planetary liquid instead of several. Also improve resource generation — right now resources often look like everything was just dumped together in an ugly pile.
