Need help finding a specific addon.

I don't have screenshot examples unfortunately, and I can't remember the videos where I've seen it. Also I'm on mobile and at work so yay. -_-

However I keep seeing an addon of some kind that keeps information on the class you play that moves with your mouse cursor. Like example would be you'd move your mouse cursor around the screen during a raid and it would have something like your current boneshield stacks (for blood DK) or combo points for rogue. I have mostly seen it on disc or Holy priest UIs but for the life of me can't remember the name of the video I was watching that had it.

Does anyone have any idea what this addon might be?
