Inventory Expansion
by Derekahedron
Inventory Expansion adds sacks and quivers that hold several stacks of items and arrows, so a player can carry more without filling the main grid.
What it does
Sacks store around four stacks of similar items. Once an item is added, the sack automatically picks up other items of the same type, and items can be assigned a sack type through datapacks. Each item has a weight that sets how much space it takes inside the sack; seeds, for example, take up a quarter of the weight of a normal item. A player selects the item to use with the scroll wheel and uses it directly from the sack, and the mod also adds two items that help keep the inventory clean.
Quivers hold eight assorted stacks of arrows. Arrows picked up while the quiver is in the inventory are added to it automatically, the player chooses which arrow to fire with the scroll wheel, and the bow can fire straight from the quiver. The mod runs on Fabric and Forge, with files for 1.20.1, 1.21.4 and 1.21.5, and the latest file for either loader is 1.5.5 for 1.20.1, published 2026-08-27. It is open source under the MIT License, and Inventory Expansion Plus requires it.
Key features
Sacks with weighted items
Sacks store around four stacks of similar items, and each item's weight sets how much room it takes up.
Automatic pickup for sacks
After an item type is added, the sack picks up other items of that type on its own.
Quivers for arrows
A quiver holds eight assorted stacks of arrows, and picked-up arrows are added to it automatically.
Scroll wheel selection
Sacks and quivers use the scroll wheel to select an item or arrow, which can then be used or fired directly from the container.
