Expanded Inventory

A wearable belt that gives you real, modular extra inventory space — attached directly to your vanilla inventory screen, not hidden behind a separate menu.

How it works

Craft and wear a belt (Leather through Netherite) in a Curios or Trinkets accessory slot. Each tier unlocks a fixed number of real, server-synced 3x3 storage modules that render right next to your vanilla inventory:

Belt Modules Upgrade slots
Leather 1
Copper 2
Iron 3
Gold 4
Diamond 5 1
Netherite 6 2

These aren't a fake preview — every module is a genuine, authoritative slot group, synced the same way your normal inventory is.

Upgrades

Diamond and Netherite belts have dedicated upgrade slots:

  • Stack Upgrade I / II — raises the stack limit inside your modules to 128 / 256.
  • Crafting Upgrade — unlocks a true 3x3 crafting grid, not vanilla's 2x2. Works in your survival inventory, in Creative, and (see below) in other menus too.

Edit Mode

A collapsible Menu control opens a drawer for arranging everything:

  • Drag-and-drop module positions, or use a preset layout (Balanced, All Left, All Right, Custom).
  • Three save slots for your own custom layouts, with undo/redo.
  • Per-module colors, plus a light/dark theme and a custom menu color.
  • Multi-select for batch operations (move, recolor, enable/disable several modules at once).
  • The Crafting module can be toggled on/off independently — no need to remove the Crafting Upgrade item just to hide it.
  • Small "i" info buttons next to each section explain what it does.
  • Mouse-wheel and middle-click-drag scrolling, so everything stays reachable at any GUI scale.

Crafting anywhere

With the Crafting Upgrade equipped, the 3x3 grid works outside your own inventory too — open a chest, furnace, anvil, enchanting table, or another mod's storage screen, and the crafting grid is right there with you. No separate crafting table trip required.
