Air Bar

As you may all know, we currently have 3 bars at the bottom left that indicate our characters; health energy, and balance bar, my idea is to implement an "air" bar to pop-up when underwater, making it easier to know how much longer we have until going back up to the surface and getting some air. As of now, the only hint we have about our air supply is when it's about to be depleted our vision becomes less and less visible, like if our character was about to pass out (which it does), so why not implement another bar that appears once, underwater, just like the blurry vision appears when dicing and while on the effects of tear gas. If it does finds it's way to the game, there could be more cadgets and/or interactions surronding that new bar, such as holding your breath, passing out if you run out of breath, etc.
