Smart Stack

A Smart Stack is a collection of related items that takes a single inventory slot. It is indicated in an inventory slot by a none-grid icon.

A Smart Stack consists of 9 slots, each of which can hold up to 100 identical items (depending on the stack size of the item -- for instance, only a single Tool can be in each Stack). A Smart Stack can be opened for examination using the right mouse button (on PC).

Items in a Smart Stack are grouped if they are identical. That is to say, they are the same Block or Item of the same Colour. For example, up to 100 Moss Green Metamorphic Rock can be grouped into a single Smart Stack slot, but they must be in a separate Smart Stack slot from the Stale Mustard Metamorphic Rock.

Shift Clicking (on the PC) on a Smart Stack will split, sort, and move its contents from the containing Inventory to a target inventory. This is useful for returning from the hunt, say, with a collection of Creature Eyes in a Smart Stack (where they will have been automatically collected) and opening up a wall of Shelves in which you have stored the Eyes with each Creature type in a separate cubby. Simply Shift-Click on the SMart Stack in your Inventory and the Eye SMart Stack will be split and sorted into the appropriate cubbies in your storage wall.
