I do feel like I spend a lot of game time moving things around in the inventory to manage encumbrance but then when you get to a trader you have to move all that stuff over to your highest charisma character because they get a higher sell price. I wish you could ctrl + click to select multiple items and then move or sell them all.
I especially hate that you can only see the inventory / equipment of current party members when you are in camp. What a pain in the neck having to ask people to leave / join the party just so you can give them a piece of equipment.
