SimpleServerSorter

Dead-simple server-side container sorting for Fabric.

Intended for use when the server runs Fabric and vanilla clients are connecting -- sorting is done through commands.

(/sortSelf | /ss) (by_id | by_group) - Sort your own inventory outside of the hotbar

(/sortTargeted | /st) (by_id | by_group) - Sort the block entity you are looking at

This mod is intended for use with vanilla client + fabric server, and may mess up on modded containers.
