Add required "source mods" to save file lists like DLC-s

[Aki Art]

Please consider adding a smaller list of icons or names of mods that are required to load a save game, like the DLC icons. I don't mean all mods present in the save, but the few mods absolutely required. For example, mods which contribute to the world generation, or mods that mark themselves as unremovable from a save file.

I made a mod using the new Subworld Mixing Settings, but my users are reporting it is inconvenient to remember which save files actually require my mod to load this world, so they are left loading the world only to crash and try again.

As our mods cannot affect this screen once removed, we modders cannot really do anything about it.

Here is a mockup of what this could look like:
