Just a quick suggestion.
I'm not sure how doable it is but if you can make it work Rare it would make accessing the barrels a little easier for some. As before when you hold an item in your hand to store said item in the appropriate barrel on the ship, why not create a function that works similarly to that? Barrel 2.0 will mostly stay the same but whether or not you want a specific resource out of a barrel or to store into one, if you hold the alike item in your hand you can only access that same item.
So if you run past a barrel with a banana in your hand you have to option to press X and only grab the bananas in that barrel if they're are any. Yes it may be a bit troublesome as you would have to keep at least one item on you to get a like item but unless there was another drastic change planned I think it would please some people.
Alternatively though if not that, then maybe have to option to set a resource priority in the menu. You set a resource to "quick grab" so you can still open barrels to look inside but you will now have a second input to solely grab you priority resource if they're are any inside.
