Update! Well, this update may look as a small one for you, but for me it's a big one. Take a look at my new portrait panels, the border is deep black and exactly 1 pixel high (or wide). I recently found out that the border named "Blizzard Chat Bubble" perfectly serves as a black border (border edge size 1). Furthermore I do have more space now for my aggro- and dmgmeter. Probably above the chats, maybe below the minimap, I'm not sure yet. There were some smaller updates, too, like changing the font in the bottom or the position of the different pitbull texts.
I do plan to change the color, it is a bit too grey, this may be caused by the Naxxramas neon colored background, but a bit more color won't hurt.
