Draxyl from the Turalyon U.S. server submits to us his Warlock UI. It's actually very reminiscent of the UI that I had for quite some time until I upgraded my graphics card and started using a lot of alpha-blending (transparency). He uses Fubar across the top with several key pieces of information and quick to reach options, and then has the bottom of the screen filled with status indicators, chat, and action buttons.
I think it's a common theme amongst most UI enthusiasts to focus the information in one or two places. This has several benefits, from limiting eye movement when trying to pickup information, to allowing more space to see what's going on in the rest of the environment.
