Addition for the player pop-up

I dunno what you really call it, but I've attached an image to show as example. I think it would be great, when you're grouped, to be able to hover over a groupie and see their health stats. Don't need it if you're on the same square, but sometimes as you're moving around, someone clicks the wrong direction, and you're in a different fight, so you can't tell how quickly you need to end your fight to go help them....
