You mean the icons, or the renaming or something else?
The icons are tweaked with IconTweaker.
Renamed by right-click and rename.
Gotta be a little more specific, cause i really didnt catch what you wanted to know..
Well I thought you used a sort of Dock program for it. So if you click the icons you open up that program or folder.
But looking at it again I think you just use the standard 'windows' way, except that you just gave it new icons and placed them in the middle. Fitting your theme better.
Anyway, the desktop is ubersweet (like lways). Would it be possible to upload those Icons you use? Then perhaps I can switch some of my icons with Yours.
