Filtermos

Picked-up items that match the filter are collected, and everything else stays on the ground. This keeps the inventory from filling with unwanted drops such as rotten flesh or cobblestone during long walks through mining or farming areas. The filter is configured in game through a visual item selector, opened with the G key or from the Mod Menu entry for the mod's config.

The filter is stored per player in memory rather than in a shared file, so each player on a server keeps a personal list. Because the list lives only in memory, it is cleared when the server restarts, and players set it again after a restart. The mod runs on Fabric and NeoForge for Minecraft 1.21.8 and is released under the MIT License, but it is not open source. Only the client needs it, so a server can run without the mod installed.

The mod's files are published for 1.21.8 on both loaders, with the most recent Fabric and NeoForge builds dated 2026-02-16. The first release came out on 2026-02-14.
