AggStack
What is AggStack?
AggStack allows you to store multiple items with the same ID but different NBT data (different durability, enchantments, or custom names) in a single inventory slot.
💡 Example: Store a 5% durability diamond pickaxe and a 100% durability diamond pickaxe in the same slot!
🎮 How to Use
Creating an Aggregated Stack
| Method | How to do it |
|---|---|
| Drag to Merge | Pick up an item with your mouse, then drag and drop it onto another item of the same type (e.g., two iron pickaxes with different durability). They will merge into an aggregated stack. |
| Auto Pickup | If you already have an aggregated stack in your inventory, picking up the same type of item will automatically add it to the stack. (Can be disabled in config) |
Viewing Sub-items
- Hover your mouse over an aggregated stack slot
- Hold
Left Alt(default) – a panel will appear below your inventory - The panel displays all sub-items in a 7-column grid, each showing its own durability bar and enchantment glint
- Release
Left Alt– the panel closes
🔧 You can change the expand behavior in config:
HOLD/TOGGLE/CLICK_OUTSIDE
Interacting with Aggregated Stacks
| Action | Result |
|---|---|
| Left Click (on the stack) | Pick up the entire aggregated stack (all sub-items) |
| Right Click (on the stack) | Take half of the top item (if stackable), or the whole top item (if unstackable) |
| Shift + Left Click | Split the stack – all sub-items scatter into your inventory (or drop on the ground if inventory is full) |
| Q (Drop) | Drop the entire aggregated stack as a single item |
Interacting with Sub-items (in the expanded panel)
| Action | Result |
|---|---|
| Left Click on a sub-item | Take that single sub-item out – it will appear on your mouse cursor |
| Right Click on a sub-item | Set that sub-item as the new top item (changes the appearance, durability bar, and enchantment glint) |
Adding Items to an Existing Stack
- Pick up an item with your mouse (must be the same type as the aggregated stack)
- Right-click on the aggregated stack
- The item is added as a new sub-item
