Sidebar upgrade
The contents of the sidebar have been upgraded. On the main page, they now include what was the top-of-page leader. Also, behind the scenes I have cut up one file kept seperately into smaller chunks, so that the seperate sections in the sidebar can be manipulated differently for different pages. The most immediate impact was that I can now easily keep the navigation at the top of the sidebar, regardless of what else is in it.
Furthermore, I can do this without having to duplicate code for different index pages.
