[Suggestion] Battery Life Notifier

I don't know how to explain the idea other than other a different company's name. So while using 'Steam' in full screen it will pop-up quickly saying "Your computer battery is low and you have ____ minutes left". I have no idea but I think it would be easy to put into the game. I'm sure for PC laptops it's easy to see that your battery is low because there is a light about it somewhere visible. However, I'm on a mac laptop and to look at the power left you have to click a button on the side of the laptop which will then blink lights to show the battery life left. Basically it's just easier to "alt-tab" but either way is something I don't do often because I'm too focused in the game to care about my battery.

So again, my idea is to use what Steam uses which is a very small (non game stopping) pop up on the corner of the screen that informs the user that their battery is almost dead.
