Probably been posted already for the first one, but-
-Accessing and changing Cargo for vehicles
-Copying Cargo to other containers/vehicles.
-Container objects such as metal cases, etc, have the option/feature to actually hold items, instead of just preset ammo boxes, etc.
-Setting everything infinite within one section of cargo, or for all.
-Saving a cargo preset and being able to paste it into other containers, similar to Virtual Arsenal loadouts being saved and loaded for players.
