DockDeamon add more space for the Dock. It brings your four pages with 18 icons positions on each. Fill the pages with your favorite applications, documents or folder and enjoy ease access to all of them.
your link to the screen shot exists.... but, it looks like a finder window, explains nothing. Could you add a few more screenshots to that page which show HOW this is "like 4 docks", how it actually works, etc.
thanks
