Addon to better show target's facing direction?

When you click on a target, it gets a circle on the ground. There’s a little pointer on the circle that shows which way the target is facing.

Is there an addon that makes that into a BIG pointer? I’m getting annoyed by bosses like Aqu’sirr that look like they’ll charge one way, then zoom off to the side instead.

You can’t get that info for mobs but there’s weakauras that can help you with things like aiming the ball on Dark Inquisitor.
