What's new

Third alpha. The headline is that uncategorized configs are now something you can act on, not just a pile you ignore.

You can now classify what doesn't match

Files that couldn't be matched to a mod used to sit in Uncategorized forever — either leftovers from mods you no longer have, or configs whose names simply don't look like their mod.

Now there's a Classify button on the Uncategorized row. It opens a screen where you pick a file on the left and a target mod on the right (the most likely ones are sorted to the top), or mark it as Ignore.

  • Nothing is written until you press Done — pick wrong and you can change your mind. Your choices are shown inline as you go.
  • Decisions are remembered across packs and across restarts, so you only do it once. They live in configswitch/mappings.txt, next to your other settings.
  • The built-in mappings ship in that same file, so you can see (and edit) them.

Fixes

  • The scrollbar in the mod list could not be dragged — it only responded to the mouse wheel. It does now. (Only the very edge of it was clickable, which made it look like nothing happened.)
  • Typing in the search box could leave the list blank until you scrolled. Fixed.
  • Searching with no results now says so, instead of showing an empty list.
  • The same scrollbar problem existed in the Backup screen. Fixed there too.
  • In the Classify screen you can now search by mod id as well as display name — useful when you remember yacl but the mod calls itself something else.

Known limitations

  • Minecraft 1.21.1 only, Fabric only, Windows only.
  • Mod configs take effect after a game restart — options.txt applies immediately.
  • Configs stored in subfolders of config/ aren't scanned yet.
  • Classify only offers mods you have installed. A config for a mod you haven't installed yet can't be aimed at it in advance.

This mod has no additional files
