The inventory management in the game is shockingly bad.

"Oh, I got a new companion. I wonder what I can equip them with."

Good luck, because the gear is scattered among your inactive companions, or the chests that might be locked to you in co-op.

"I need to take a potion mid combat"

It's somewhere in those 20 inventory wheels!

The whole inventory weight is kind of pointless as well, since you can send to camp at any point, and there's very few places where you can't just go back and get something. It's just inconvenience kept for the sake of following some arbitrary rules.

Gear especially should just be kept in a separate place from consumables and quest items, with maybe some quick swap wardrobe feature for e.g. switching to a bludgeoning weapon for smashing walls.
