Ubuntu Netbook Remix Mockup

Can Ubuntu Netbook Remix look like this? I would love to see tabs on the side. When you clicked on the Places tab, it would replace the left navigation list with places such as home, Desktop, Documents, Bookmarks, and any inserted media. In the right large content area, there could be a simple file browser that would allow you traverse folders and open files. The contact tab would pull contacts from evolution, thunderbird, pidgin, or empathy and allow you to edit contact. Don’t know if this is possible but I hope to look into it. Have to brush up on my C and look at the clutter library.
