I became a fan of Power Auras in WoTLK and when anyone has asked for something to track such and such i say get power auras.
I installed the latest one manually and lost all my previous 4x auras but creating new ones is a challenge and a learning curve - the only thing that I see causing people to get all upset is not knowing where x is when your trying to find it.
I was totally lost without Power Auras since the patch and i am glad it's back
As others have said about lining things up - i use Quartz and Bartender - unlocking bartender i can place an actionbar as a guide line on my screen and just pop the new auras on that line
