I still don't understand this one. Inventory management in this game is a joy. I have pretty much all the tools I need. The only thing missing is labeling containers.
Think of the following situation: I find an item for companion X. But companion X is not in my party. So I have to go to camp, run to companion Y make them leave my party, then run to companion X, add them to my party, give them the item, make them leave my party again, run to companion Y, add to my party again and then leave camp.
It gets a lot worse if I have items in my group's travel chest or want to compare items across all companions.
The easiest solution would just be: Once I am in camp, I can access all inventorys (indepentenly if the companions are in my party or not)
plus the groups chest at the same time. This way I can properly compare all items on each companion and don't have to run a marathon in the meantime.
