A small, focused tool for anyone drowning in a huge Penumbra mod library who just wants an easy way to keep it organized. Instead of dragging hundreds or thousands of mods around one by one inside Penumbra's UI, you scan your library once, then reorganize by creator, type, or your own custom rules, with bulk moves, undo/redo, and one-click strategies to do the heavy lifting.

It's built to be safe by default. Everything is a proposal in memory until you explicitly apply it, every apply is guarded by a dry run and a verified backup, and you can protect specific mods or whole folders so they're never touched no matter what strategy you run. If anything ever looks wrong, restore a backup and you're back to exactly where you started.

It never touches your actual mod files or library folder. It only reads and writes Penumbra's own configuration, the same data Penumbra itself relies on to know where things are. Your .pmp files, textures, and physical folders stay exactly where they are. Only the virtual organization inside Penumbra changes.

It's unofficial, beginner-friendly, and meant to stay out of your way otherwise. No game files, no collections, no priorities. Nothing beyond the one job of making a big mod list easy to navigate again.
