About this Mod
Inventory Expansion
Form to request compatibility with other mods
Adds two new items to help keep your inventory clean.
Similar to the bundle, sacks and quivers can store items inside them, but each have their own utility.
Sack
Sacks store around 4 stacks of similar items. Items are given a sack type via datapacks. After an item is added to a sack, the sack will automatically pick up other items of the same type. You can also use items directly from the sack, using the scrollwheel to select which item to use. Items are also given weights that decide how much of the sack they can take up, such as seeds taking up 1/4 of the weight of a normal item.
You can craft the sack with 6 leather and two string

Here are examples of various sack types:





You can also dye the sack:

Quiver
Stores 8 assorted stacks of arrows. Can fire arrows directly from the quiver with a bow. Picked up arrows will automatically be added to the quiver.
You can craft the quiver with 1 string, 4 leather, and 2 rabbit hide:

Just like the sack, you can select which arrow you want to be fired from the quiver by usign the scroll wheel.
