The Site Shaper is a fresh install of WP that will give you all the demo content, plugins, and settings. If you are trying to understand how the theme works, I suggest installing the shaper in a second location and poking around in the admin.
These releases are designed to use widget positions and automatic layout calculations instead of per-page layout templates. If you use
Widget Context to show/hide widgets on specific pages, the framework will automatically reposition and recalculate the measurements for the layout for you.
