Now that I think about it, I wonder if that's why they made the change where you can't access companion inventories in the tutorial. Because of multiplayer. If there are already four PCs, then maybe they don't want the inventory screen getting too crowded.
I don't think it has anything to do with it. I guess the idea is just that they don't want you to be able to manipulate the inventory of "temporary allies" that are not fully on board as a companions. Which is occasionally inconvenient but makes somewhat sense.
Party control in Baldur's Gate 3 is a complete mess that begs to be addressed. SAY NO TO THE TOILET CHAIN
