1. There should be a special kind of key that breaks upon use (creative only). Would fit well in some maps, where you e.g. should find a door that requires a key, and you get that key, but after opening that door you are left with that key, which you will not use again because that key was only for that door. Dropping it and waiting for it to despawn or throwing it into lava would look weird.
Where can i find your upcoming ideas list?
