Creates startup mod settings for each planet to mark them as visited.
By default, replaces all non-starter icons with a red cross. Ticking a planet in the settings will stop this change for any items unlocked by that planet.
Top settings toggle what changes are made to locked items.
Bottom setting is a toggle for all unrecognised planets.
The list of planets will only show installed (and supported) planets.

If you have a planet you would like added to supported ones, see the thread in the discussions to request it - you will need to provide me with the name of the mod (in the mod portal), the name of the planet internally and the name of the planet in a human-readable way. E.g:
space-age, nauvis, Nauvis
planet-muluna, muluna, Muluna
secretas, frozeta, Frozeta
metal-and-stars, Mirandu-A, Mirandus
