This screen is where you can view and manage items which can be obtained via Looting or the Black Market.
Items
The Items tab has two sub tabs with the option to show the items you currently own (default), or all items in the game.
You can select an item to see more details and sell or discard the item.
Pinning
The "Pinned" option when viewing an item will keep this item pinned to the top of your inventory, ideal for items you want quick access to.
Locking
The "Locked" option when viewing an item prevents accidental selling or discarding of this item. The option to sell or discard the item will be hidden and it won't appear in the Bulk Sell tab.
Note: Locking an item doesn't prevent it from being used in other areas of the game, e.g. selecting as heist equipment.
Bulk Sell
If you're a Certified Gangster, you'll have access to a Bulk Sell tab. This tab allows you to sell different items at once, or your entire inventory.
The "Trim" button can be used to retain a certain number of each item and sell the rest. For example you may trim your inventory down to retain 10 of each item.
Using items
You can use items in the following places currently:
Note: Items are usually single use, so you won't retain the item after using it.
