[Feature Request] Custom/Secondary mod library (for incompatible mods)

[Jitsuryoku]

At the core my idea is having some locally saved mods show up in mod manager in its own category. This would enable easy re-install of mods that are still technically compatible, but have not been tested yet (or have been forgotten while still working). BailOutMode, CustomSabers and SaberFactory often fall into that space where they still work just fine, but you have to manually copy them into Plugins folder.

Most basic version is a folder that users would populate with mods manually (Updates would also be manual). Mods in that folder would show up separately regardless of current official compatibility.

When installing mods there might be an option (additional checkbox?) to save a copy of selected mods into that folder (to enable easy backups), but this is out of scope for my suggestion.

There might be an even better way of doing this that I'm not seeing.
