Add on that lists available targets in range?

I've been lookign for an add on that will list targets that re in range like Proximo does for the arenas. When I am running instances i find meself hating tab and mouse targeting during multi mob pulls.

I did KINDA find one that is close to what i want. its called Personal Sentry, but its not quite it. The big issue is that it will add any enemy with the same name as ONE target, so if you click the popup name your 50% of the time on the wrong target.

Anyone have an add on like this or the skill to write it?

I accedentaly reported this post instead of replying it. My webbrowser was kinda funky (using a terminal server) so I didnt realize before now. Please just ignore my report :P
