Recently I installed PowerAura's to get a bit more performance out of my Druid. I'm still exploring most of the addon's functionalities but so far I have been able to create a few very basic but useful aura's that help a lot during boss fights!
As you can see I have four basic aura's up (they only show while being in combat, I used the "test all" command in the screenshot).
The exclamation mark (light green) is basically a small warning when I do not have a single LB stack running, by creating this I increased my LB uptime by nearly 10% on some fights (yes, I was a bit failing on that bit). More LB uptime = more Revitalize proc's/Omen of Clarity proc's!
The bright green inner aura is OoC, I disabled the standard Blizzard one because I didn't fit with PowerAura's. The little green timer (same colour) shows how long I have left on my OoC proc before I lose it.
The light blue aura is actually two aura's, one proc's when I go under 81% mana (for innervate) and the other one proc's when I have below 25% mana (ow ow time to panic). Basically when I have one blue aura up I can use Innervate on every single cooldown without having to worry that I'll cap my mana and lose on Innervate regen.
here's the code if you want to copy my aura's!

I'm still playing around with this but I might add a PowerAura section to my guide if I find more useful stuff!
