More use in bats

I think Mojang should add the "Bat Wing", you can obtain the Bat Wing by killing a Bat. you can put the Bat Wing in the Brewing Stand, the Bat Wing will help you make the "Cave Vision / Bat Vision" Potion. Just like bats, they see very well in the dark, but they're completely blind when it comes to sun light or any light source, so the potion will be great when you explore the underground, but won't be as great when the sun is rising outside, so it's just a simple and fast way to make a night vision potion, not as great, but simple. Besides, Bats need more use than just wander around in caves.
