how to recreate: set interface in minecraft settings to 1 or 2, maximize minecraft window, go to mod config screen

Hey! Thanks for taking interest in the project!

This is because Minecraft buttons have a limit of (I think) 400px width so I'm not sure it is possible to correct for, but I'll look into it.

Also, I don't know how you actually got a jar as it hasn't been published yet, but you can get it from my snapshot repository with the version of the commit. https://maven.isxander.dev/#/snapshots
