AOE Ground Target Ring addon?

[Duplomancer]

Anyone know of an AOE Ground Target Ring addon? I would like to make it more visible.

Note: I am NOT talking about the Gameplay > Combat Custom Color

Consider the following, reasonably easy to see scenario:


Now, not so easy:


It would be cool to be able to thicken the line and change or intensify colors. Sadly my coding skills are rusty as hell. I poked at the API but could not find anything except 2 references to GroundTarget. One was for Mode (presumably for quick cast) and the other is for error handling. Maybe it is considered a reticle?
