Mixed Stacks

by ANAHKEN

Mixed Stacks lets similar items share one inventory slot, so charcoal and coal, or two of the same item, no longer each take a separate slot.

FabricClient and serverCC0 1.0 UniversalOpen source1.21 – 1.21.1

What it does

Items that are alike can be combined into a single stack, which frees inventory space that would otherwise go to near-duplicate entries. Pairs such as charcoal and coal can be merged through the compatibleItemPairs setting, and tags can be used to group items under tagKeywords. The default config covers the common pairings.

Servers that run it need every player to install it too. It is released under CC0 1.0 Universal and is open source, with a public source code repository and issue tracker. Cloth Config API and Mod Menu are optional and add a settings screen when present. Files are published for Fabric only, for 1.21 and 1.21.1.

Key features

  1. Combined stacks

    Similar items can share one inventory slot, which reduces clutter in storage and in the player's hotbar.

  2. Custom item pairs

    Specific item pairs can be added through compatibleItemPairs in the config file.

  3. Tag-based grouping

    Items can be merged by tag using tagKeywords, so whole families of items can combine without listing each one.

What the author says

We've all been here before. You have 2 of basically the same item (e.g. charcoal and coal), but they take up 2 different inventory slots? Introducing... Mixed Stacks! You can add specific item pairs via compatibleItemPairs, or specify tags that can combine using tagKeywords.
