Kona...the thing about LS is that it is a whole shell....and is highly configurable to anyones whim.
When a theme is complete...eg the recent Mac OSX one....it can have 500 or more files involved, making it a significant effort on the part of the skinner/themer....and generally well worth waiting for.
Feel free to stick with your Explorer....[mediocrity suits you]....and leave the weirdos to their alternate shells....
