LF an addon

[saphirre12]

I am looking for an addon that will show you unit frames of each mobs when you pull a group . The idea is when I was in ICC , I pulled a group with at least 10 mobs and I can easily see which one I lost aggro by looking in Tidy Plates . However , it's not easy to click on them or I can tab but I won't get to that specific mob by just one tab .
If we have unit frames of each mobs in the group that show which mob I lose aggro and I am able to click on that unit frame to target the mob , it will be so much easier

Do you know any addon that can do this ? Please tell me . Thanks
