Item Sorter
Item Sorter is a Forge storage mod that places a single block in a hopper chain to sort items by filter, replacing a multi-stage setup built from vanilla parts.
What it does
A sorter block sits under a hopper chain and connects to the hopper above it. Items pass through its filters and are pulled out of the hopper toward the storage containers below, so one block can handle a job that otherwise needs several vanilla stages. The block works much like a regular sorter, with one key difference: it ignores which slots are locked, so a locked slot does not stop the hopper transfer.
The mod is aimed at players who sort items in automated storage, and at server owners who want the same sorting behavior on a shared world. The sorter is placed under a block inventory and filters what types of items are pulled from the hoppers into the storage containers. A GIF in the project's description shows several filter setups and how they solve common sorting problems.
Item Sorter is published for Forge 1.20.1 only, with version 1.0.0 as the latest file. Installation covers the server and each player's game. The code is open source under the MIT License, and the project has public links to its source code and issue tracker.
Key features
Single-block item sorting
One sorter block replaces a chain of vanilla hoppers and filters for many sorting setups.
Hopper-chain placement
The sorter is placed under a hopper chain and pulls matching items out of the hopper above it.
Additive and subtractive filters
Up to five filters can be used with the sorter's filtering mode set to Additive or Subtractive. Additive lets matching items pass, while Subtractive lets everything except the filtered items pass.
Ignores locked slots
Unlike a regular sorter, the block disregards which slots are locked, so transfers continue regardless of slot locks.

What the author says
This block is simple. You place it under a hopper chain and it connects. If the hopper above has any of the items that pass its filters, it will pull them through. It's a single block solution to a multi-stage problem in Vanilla. ## The Advanced Sorter This block functions like the regular sorter, but with one key…
