Need help tracking down an addon

[zeb7s]

Hi, just recently came back to WoW again, and just got done redoing all my addons.

I'm not sure what mod actually did it, but on my old interface every time I looked at an equipment tooltip besides each stat it would have text saying what the difference was from the gear I currently had equipped.

For instance if something had +32 stam and my current equipment had +40 it would say (-8 Stamina -"xx" HP)

Now that I'm leveling my new DK I am severely missing the convenience this addon provided so I would be extremely thankful if someone could point me in the right direction!
