Expanden Inventory

Modules are placed in a layout the player can drag and drop, starting from a preset named Balanced. Three save slots keep separate custom layouts, and undo and redo are available while editing them. Each module can get its own color, and a light or dark theme sets the custom menu color. Batch operations let a player select several modules at once to move, recolor, enable or disable them together. The Crafting module can be switched on or off independently. Short help buttons beside each section describe its purpose.

Belts are craftable from Leather through Netherite, and Curios or Trinkets provide the accessory slot. A higher belt tier opens a fixed number of real, server-synced modules. They are genuine slot groups, not a preview, and they render next to the vanilla inventory. A collapsible Menu control opens a drawer that arranges everything. Diamond and Netherite belts add dedicated upgrade slots, and Stack Upgrade II raises the stack limit inside modules.

Expanden Inventory requires Architectury API on Fabric, Forge and NeoForge, and Fabric API on Fabric. It runs on the client and the server, so both need it. Files exist for 1.20.1, 1.20.4, 1.21.1, 1.21.4 and 1.21.11, and it is released under the MIT License, but it is not open source.
