Don't get TOO far out of the way
One thing I'd quite like to know about is when my battery is about to die.
On earlier versions of Windows, there would be plenty of warning. Too much, in fact - front-and-center dialogs that I'd hit 30%, then 15%, then 10%... If I ran out, it wasn't for lack of warning.
Win10? Not so much. Unless I choose to look bottom-right, the first thing I know about it is my laptop going into hibernation. Yes, there's an icon, and it has a tiny (4px?) "critical" overlay when things get really tight. But unless you choose to look, you never see it.
Perhaps there's a setting somewhere in the abomination that is Settings? I've looked, and not found.
