Top request for me even though I dont have much time in the game yet:
-Sort by type
-Compare with equipped (MUST HAVE! I mean come on!)
-When you have choosen your sorting option, AUTO SORT the inventory
-Sort stash, I'm a packrat too and I'm pretty sure most of us are in these types of games
-Quest indicator ("!") on top of NPC with quests (that could be disabled in the options)
-On console, the cursor on the map should move way faster. I don't know if it's related to your sensibility in-game, but it shouldn't. Like its a crawl going through the map when it should be a higher sensibility but I want it way less sensible in-game.
-Personal marker on the map
-Track multiple quests at the same time. Or just every quests is tracked but with a different color on the map (green = tracked, red = other quests)
