A while ago I was helping a friend get a grasp on the benefits of customizing your UI, and decided to show him what I had done with mine. It wasn't until that point that I realized I MAY have gone overboard. lol. :)
At any rate, I figured I'd share what I've got set up here, and field any questions / suggestions should anyone have any. There've been a couple tweaks since I created these layouts, but only minor things.
