Healing inc mod/unitframes?

[goldengamer]

I know I've seen it somewhere before part of the unit frames that I was using, or another mod. I currently have Xperl, but it will only show a green border around the unit frame when a heal is incoming. I was wondering if there's a mod or different unit frames that will show an estimated amount of health to be healed inside the health area? If that makes sense xD Like you say 1 persons got 50% health, and your heal can only do 30%. 30% would be shown green inside the hp bar before its healed.

Its mainly since I am a shammy atm, and I don't want to end up overhealing too much. So if I can see incoming heals I wont keep casting on that target

I usually use VisualHeal and pair it with LibHealcomm I think it was to show heals and estimated healing etc.

Xperl shows that too if you got the LibQuickHealth-2.0
