Tried this in a space exploration save. Only showed Nauvis. Not unexpected.

But this is exactly what I want otherwise. Surfaces in SE seem to me like they should be consistent, even if the icons would be janky and there would be a dozen garbage surfaces I would need to manually blacklist.

It's certainly not impossible, but the main difficulty is definitely the icons. SE just has the generic "planet" and "moon" icons, so there'd need to be some solution to dynamically generate unique icons for each planet.

Maybe if it's possible to read the automation ID of each planet...
