I created this skin to take advantage of several of QCD version B33's new skinning features. Primarily, this skin offers a total of 5 different extensions, most of which overlap one another to provide different features in the main window. The main modes are song information, playlist, visualization, and EQ settings. It's also got a pop-up search window that's accessible from any mode (Search - a first for my skins!).
Additionally, the playlist's track background takes advantage of the new ability to have custom alpha settings. As an example, the font turns from normal to a brighter italicised version when you hover it - the background doesn't change at all because it's completely transparent.
A really minor change is that the external visualization window now has a customized color and background. This won't be noticeable unless you've just started up the player and no songs are playing yet. Still, it looks way better then a white background would.
I wanted to make a mini mode for this but ran out of steam. Perhaps I'll do that later and release an update.
Note that you MUST have Build 33 or better of QCD to use this skin! Get it from [LINK]
