Stackable Items

Stackable Items changes the stack size of many items that normally stack to one or sixteen, so a single slot can hold 64 of them. Items obtained from creative inventory, loot chests or mob and block drops are covered, as are items stored before the datapack was installed. Dropped stacks stay together on the ground and can be picked up again as a group. Chest boats, hanging signs and music discs are among the affected items.

Recipes that use the modified items are adjusted too, so a chest boat can be crafted from stackable boats. The recipe book auto-fills the crafting grid as usual, and recipes the player can craft normally still work without auto-fill. Buckets are the exception: they keep their default stack size, which keeps emptying water and lava buckets in a furnace or crafting process working, and milk bucket and cake recipes unchanged.

The mod is server required, with the client optional. It needs Fabric API on Fabric. Files are published for Fabric, Forge and Quilt, covering 1.20.5, 1.20.6 and 1.21, and snapshot builds are also published. The mod is released under All rights reserved and is not open source, though public links to its source code, issue tracker and wiki exist.
