Hello!
Thanks for the mod!
There is a request to make a check for planets in the mod settings, if the mod with the planet is active, then the setting is present, if there is no such mod, then the setting for this planet is hidden.
You can access the "mods" variable in the settings stage, so you could either make the setting(s) hidden, or not even create the setting(s) at all, if the relevant mod isn't present.
