LF calculator - health/mana, health/secFollow

I'm looking for a link to the priest calculator I've seen that lets you input your talents (and other armory info, i think), and it will calculates the 'healing per mana' and 'healing per second' of each rank of each of your spells...

I remember seeing it in a discussion of weather Heal Rank 4 was a good spell to use at level 70 (instead of Greater Heal, I think). I'm pretty sure it was somewhere here on allakhazam.

I don't recall the name of the addon, and I can't check since my computer randomly locks up whenever I run World of Warcraft now, but the addon gives you a lot of math in-game for each spell.

Oh, just checked the interface folder of the game. It's called "DrDamage."
