Smelling (A new concept)

Minecraft is open to many of the weirdest and most interesting concepts that would at least make the game a bit more enjoyable, I propose an idea that would fit that category: Smelling. Smelling would be a brand new ability for your minecraft players to have, you would be able to assign a hotkey to the function. You would have to hold the button (or it could be toggleable) and you'd get 5 seconds of smelling your surroundings and it'd have a 20 second cooldown.

During the 5 seconds while you smell you'd get a brief idea of what is around via scent of something that is about a radius of 3-10 blocks away from you. I know that you'd be able to see that far away, but smelling would be different, you'd have a chance of smelling an item you couldn't see with your eyes.

Now Dogs/Wolves would have a greater scent radius of about 60-105 blocks away and would be able to find new items that you'd have to be really close to smell. To keep this from being an overpowered feature is to make the new items that you could smell very very rare.

About the items that you would be able to smell would have to be an idea for another post or rather in the comments of this post. But I'd feel you'd be able to smell a zombie or animal near you if you tried to.
