Woppers

Smart hopper filtering and speed control through simple anvil renaming.

Overview

Woppers enhances vanilla hoppers by allowing players to configure filters and transfer speeds through simple anvil renaming.

No commands. No GUIs. No menus. No extra blocks.

Simply rename a hopper in an anvil, place it, and Woppers automatically applies the configured behavior.

Designed for survival servers, technical players, storage systems, item sorters, automation builds, and large-scale farms.
