The "Look & Feel" item of your site's "Layout" menu had grown unwieldy as we added more choices. We've retooled this page to make it easier. Click for more information.
Rather than a giant page of templates and color schemes with editing controls, we've broken them apart into tabs. The Templates tab has the template options - click one to bring up a real preview of what your site would look like with it, which will give you the option to activate it. The currently activated layout can be edited with the "Edit Template" button.
The Colors tab allows you to choose a color scheme, and will only appear if your current template supports custom colors.
The Widget Box Design tab used to be on the "Front-Page Layout" item of the "Layout" menu, but that page was no longer needed since we widget-ized your front page, so we gave it a new home here.
