Not to be mistaken for #8, a more advanced version of this.
Basically, whenever you want to track whether or not you have a certain item that is specific beyond normal use, you can add a Basic Custom Item, which contains a name, description, and also whether or not the item is one of a kind (no amount tag and no adding/removing an amount of the item). You can add and remove an amount of any key item (if they're not one of a kind), and you can also delete key items if you don't want them in your key inventory anymore.
May be superceded, or at the very least: Merged with the original issue.
