Bundle Up
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Bundle Up!
A simple and lightweight Fabric mod designed to do one thing, put your items into bundles! Open your inventory and press the keybind Default: B to store your items quickly and efficiently.
Configuration/Specific Behavior
- It does not pull unstackable items
- Specific inventory slots can be blacklisted to disallow bundles from taking those items. The hotbar is blacklisted by default.
- There are two main modes of the mod
- Default (not holding shift): Priority goes to items that will take the least space in the bundle, freeing the most inventory space possible.
- Sorting (holding shift): Items can only be moved into a bundle if they are already present in that bundle. Sorting mode is space efficient as of v2.1.0
Commands
/bundleup modifylist (add | list | remove) - Adds your held item to the list | Outputs the current list | Removes your held item from the list
/bundleup listmode - Toggles the list between blacklist and whitelist
/bundleup sortingmode - Toggles the default sorting mode (inverting shift behavior)
