After ~450 hours in the game, I realized something that I’d been wanting was in the game the whole time, just not explicitly: a way to put your items into “folders”.
I often wondered what the purpose was of placing empty backpacks and pouches throughout the game and making them show up in the alt-view. I figured they had items in them at different difficulties or previous versions, or they were simply there for aesthetics (I think most likely option). It only just occurred to me that I could pick them up and store items in them to sort out my stupid long inventory lists.
Gale has a backpack with all his little scrolls. Lae’zel has a backpack that somehow holds 20 daggers, 12 javelins and a spear. And astarion has a pouch with with enough magical arrows to make the Fat Man look like a firecracker. Now the stuff I actually plan on using is much easier to find.
Pro pro tip: Bags bags bags and Better Containers (and his whole suite of “better” mods)
Be careful putting quest items in though. I had one of the nether stones in one, and an update glitched the mod causing the bag with the stone to disappear and soft locking my game (until I downloaded the cheat engine to flip the game state, but it was a very close thing).
