Stefanka's shellstyle

Hy everybody

I was looking into stefanka's shellstyles(the one with the longhorn like common places bar) and i was wondering if it it were possible that someone explained me how to add the preview pane again cause i love that

one.I just can't seem to find the code that makes it dissapear.

Or someone can explain me how i can make the whole sidebar thing on top like longhorn without losing any of the options within the pane.

I know its a bit hard to understand but please....
