Use GLASS scrollbar images for the scrollbars on the taskbar and on fences. And pleeaase sort out the "Non-Captioned Window edge" (used for Window Previews in Vista). And I'd like to be able to skin the background of the Alt-Tab switcher. I'd also like transparency and blur in "taskbar group menus" and "start menu pop up menus".

Also, use MASKS to tell glass windows, the start menu, taskbar and other glass areas where to blur thus enabling completely transparent blurred start menu and other menus, irregularly shaped windows and completely.
