I'm sure we've all been there; you have so much shit in your hoard, it's just a pain to scroll through it all to find what you need. Sure, you could control f to search, but what if your device can't do that?
So I'm suggesting a little "Search" box in your hoard in which you can just type out the item you're needing. It shouldn't clutter anything up and will make using items a hell of a lot easier. It'd be more helpful if it were coded like the Wardrobe, in which item suggestions start popping up as soon as you start typing, but I know that can be a bit of a pain on mobile anyway.
