Running around with a filled Gasoline Canister, searching for the hard-to-find V3S Truck gets frustrating, because every Time you log in or choose an other Action or draw a Weapon for Self-Defense, picking up the Canister shows 'empty Canister' Option at first. It happens way to often, that the Fuel is spilled into Nature by that for no Reason and one has to find a Gas-Station again to refuel.

Showing 'fill Canister' at a Gas-Station and 'Refuel <VehicleX>' near a Truck or Car or what-ever-to-come in later Updates would be perfectly enough IMHO, spilling Fuel into the Environment is never a good Idea in Real-Life, why should it be in Chernarus?! Why can't a Canister filled with e.g. 8L Fuel simply be filled up, instead of emptying it to 0% first and then filling it up to 100% again? This seems slightly illogical, not to call it ridiculous.

A Function to refill a Canister by another Canister might come in handy also. This works with Canteens and Waterbottles, so it surely could work with Canisters also, i presume.
