Window Inventory
A window inventory displays items in a toggleable window (by default, the Tab button). You can hover over these items to display their name and description on the right hand side, and if setup, even inspect them.
Setup
First, make sure you have setup an Inventory Controller.
To add a window inventory, simply drag the InventoryWindow prefab into your scene, which is located in the Core > Prefabs > Inventories folder.

Note
The GameObject does not need to be a child of the ExplorationToolkitManager, as this is not a registered system.
