Functional Storage
Your classic storage drawers but with more upgrades!. Free Minecraft Java mod for 1.21, 1.21.1, 1.20.1.
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.

Functional Storage is an alternative take on the storage solution of Storage Drawers with an updated look:
- Pulling Upgrade: It pulls items from an adjacent inventory
- Pushing Upgrade: It pushes items to an adjacent inventory
- Collecting Upgrade: It collects items on the ground
- Armory Cabinet: It stores 4096 non stackeable items(by default) and can only be accessed with external tools (currently) like Applied Energistics or Refined Storage external storage tools
- Storage Upgrades: Have changed a a bit, there a less types of them but they give a bigger boost
- Storage Controller: You can link drawers to it without having direct contact (Range can be extended with upgrades)
- Fluid Drawer: Stores Fluids
- Controller Access Points: Acts as a Storage Controller when linked to it
- Simple Compacting Drawer: Its like a compacting drawer but with only 2 slots

How to use
- Drawer controller: To link a drawer to a drawer controller you need to use a **Linking Tool **
- Ender Drawer: You can copy a drawer frequency by left clicking it with a Linking Tool and then you can right click another Ender Drawer and then they will have their contents synced
- Linking Tool: Right + Clicking a controller to configure it then you can link Normal/Compacting/Ender Drawer to a controller by Right Clicking them if they are in range (8 radius by default)
