A few months ago I begun changing the site from a tables based layout to a css and divs based layout, one of the few remaining layout tables was removed today, the breadcrumbs and page last updated line on each page has now migrated into a shiny new div.  It's a change that unless you view the page code is unnoticeable but it's a change that along with the other page layout changes has more than halved the page sizes, which means the pages should load that bit quicker.
