healbot, useful if you do any kind of heal function

How the hell do healers do anything without Healbot? I can't stand having to F-key through people's names, then find my number keys to cast stuff.

Healbot's a great addon. It brings up everyone in the raid's name with their healthbars in a nice little color coded block. All you gotta do is click on the name and it will cast a spell on them!! It's super customizable too. For examples:

Skarrina:
left click - Dispel Curse

Tetra:
left click - flash of light
middle click - holy shock
right click - holy light
shift + left click - beacon of light
shift + middle click - lay on hands
ctrl + middle click - cleanse
etc

In addition the blocks display the current buffs you have applied to people and their remaining times, and also any debuffs that you are able to remove

Healbot is on curse.com somewheres.
