A library of common functionality used by my mods, in one place for easier maintenance and faster updates.

This mod requires Fabric API

Main focuses (and basic user-friendly descriptions):

Multithreading (Allows more things to happen at once)
Serializing and deserializing data (Makes it easier to save various data and create config files)
Translation management for client-side-optional mods (Makes it so even if you aren't required to have a mod installed to join a server that's using it, you can use it anyways if you want to use a different language than the server uses)
Common code to make it less tedious to make commands and config GUIs

More details for developers can be found on the GitHub.

How does this help users?

Lower risk of bugs because the common functionality is in one place instead of copied to a bunch of different places
If a bug is found in this common functionality, it can be fixed once instead of having to be fixed in a bunch of different places.

Does this do anything on its own?

It shows up in the mod list, but that's about it.

Do I need to download this to use your other mods?

Yes, for the following mods:
