Smart Filter
Smart Filter lets a player decide which items the inventory picks up, using a whitelist or a blacklist built from filter items in a 9-slot GUI.
What it does
Each filter item is configured in a chest-style interface with nine slots. A filter registers an item type without consuming the real item, so a player can set up the list without losing stock. Clicking an item in the GUI with an empty hand removes it from the filter, and the system merges duplicates so one item type never takes up more than one slot.
Players can carry several filters at once and use them for different tasks, such as one filter for ores and another for wood. Whitelist mode picks up only the listed items, while blacklist mode picks up everything except them, which helps keep cobblestone, dirt, seeds and similar junk out of the inventory. The mod is built on NeoForge data components and tri-state logic, and it runs on client and server with Forge and NeoForge files published for 1.20 – 1.21.11.
The client and server both need the mod, so it has to be installed on each side of a multiplayer server. Smart Filter is not open source and is covered by All rights reserved, and its files are published for 19 release versions.
Key features
Whitelist and blacklist modes
Switch between picking up only listed items and picking up everything except them, without rebuilding the filter.
Ghost slots in the filter GUI
Filters register an item type from a click, so the configuration never removes stock from the inventory.
Multiple filters at once
A player can carry several filters and run them side by side, one for ores and another for wood.
Automatic duplicate prevention
The filter list stays sorted and merged, so the same item never occupies two slots.
Quick removal from the list
Clicking a configured item with an empty hand removes it from the filter.

Use cases
Clearing out junk drops
A blacklist can reject cobblestone, dirt and gravel, leaving room for ores and valuable drops.
Sorting harvest by type
Separate filters can collect seeds, crops and wood in one pass, so a farm run fills the inventory with the right items.
Who it’s for: Players who gather resources in large worlds and want the inventory to take only the items they choose. Server owners running heavy modpacks can also use it, since the mod is described as light on performance.
