Add a ‘quest item’ hotbar button to the default UI. Anytime I have an item that I need to use during a quest, it goes into that slot. Nothing else can be placed there. The slot should be located somewhere above or near the actual hotbar(s). Bonus points if the slot dynamically changes based on the proximity of a quest objective in the event that I have 2+ of such items. Also feel free to remove the quest item(s) from my bag and store them someplace else, since I don’t find quest items cluttering my inventory ‘interesting gameplay’.
