ok, something I can't believe that I kept forgetting to mention, dispite being one of the ONLY things in the game that I think is actively bad.
When your inventory is full, or almost full, the text saying that you can't pick up that item MUST say what it is that you can't pick up at all times. Additionally, the text for haveing too many of the same item at once needs to have priority over the general message.
Something that happens way too often is that I go to a chest, attempt to pick up an item, get told my inventory is full but not be told what the item is, drop or waste an item, and try again only to be told that I'm carrying too many swords. That needs to be addressed, so I know if I even want the thing on the ground that I don't have space for.
