Here are answers to a couple of quick questions raised by your eagle eye Boom:

2 Chat windows : The first (left) is strictly for party, raid and guild chat with no other distractions included. The second (right) is made up of a small group of tabs for everything else... i.e. general, trade, boss text, says, yells and etc. One of the tabs on this side is indeed the combat log, while another is a special Blood Queen tab, that I set up to work with the bite mod. So.. the left is focused communication, while the right side, is my all-purpose/catch-all side. I'm weird and I hate excessive scrolling.. So, as much as is reasonable, having two wide chat frames suits me well.

Power Auras: You're right that all of these particular screen shots show a similar image - which is that my battleshout is active (except for the ICC raid shot which shows a similar but different color aura telling me that the blessing of might is operational and is replacing my battle shout. Its set like this so that I can monitor it without having to, mid fight, look at the top of my screeen). What's not shown is that I have 5-6 more, very distinct auras that show up during certian abilities and procs. The trick here was to make them all unique enough that I could distinguish each ability/proc while having them layered on top of each other and also still be able to see through them to the environment beyond. This is where the different graphics, color and animations of the auras comes into play. Too bad these screenshots don't show all of that in action, but its hard to capture a good pic with everything firing off.

That all said, don't worry with all of this installed, my addon memory is still below 15 mb and my comp. is beastly enough to handle it all. :)
