Fermium Booter Mod is a simplistic mixin mod utility to allow developers to load mixins both early and late, allowing for modifying classes that normally could not be modified otherwise.
Features:
- Adds the ability to toggle mixins prior to application through the use of a Supplier, to allow developers control over optional mixins.
- Adds the ability to remove other FermiumBooter mixins from applying, for testing or tweaking purposes.
