MrDeadPools Filter Hopper

Each filter hopper holds five ghost slots, and each slot can be set to a different item template at the same time. Only items matching a template are moved; everything else is blocked. Right-clicking the hopper opens its settings, and the templates are filled from the items the player already holds. The hopper works in the same directions as a vanilla hopper, taking from the inventory above and sending items to the block it faces.

The hopper stays inactive when no inventory sits on the side it faces, so placing a target chest or container is what starts transfers. Filter templates are saved with the world and restored after a reload. On multiplayer servers, players see the same templates in real time. The mod needs NeoForge and no other mods. Files are published for NeoForge 1.21.1 only, with 1.0.1 as the latest file, and the environment is client and server, so the server and every player need it. The mod is released under All rights reserved and is not open source, although its source code is publicly available.
