Here is KDE Control Center Ideas. This inspiration came from Amarok Context browser tab and Metabar (http://www.kde-apps.org/content/show.php?content=21168).
Its only screenshot that i modified with Gimp. Because the tree icon for choose configuration
in control center look old fashion for me. I hope the next control center tree browser change into new design and can give the beautifull look and feel.
Have Fun with KDE
