Hopplet

Hopplet is a Paper plugin designed to allow more simplified and expressive item filtering than vanilla allows.

It features an easy to learn filtering language designed for the sole purpose of filtering items based on their properties.

Filters are edited through an intuitive user interface where you will receive immediate feedback on whether your filter will work or not.

You can learn how to use Hopplet at the wiki here. You can also ask for help with designing filters in our Discord.
