As you can see it's now nothing like the base layout (the author even helped me set up the flash area on the left - he takes small donations for tech help etc).
To answer your original question, no, I'm pretty sure there's nothing quite so configurable from the Dashboard. The author's done a really good job of making a lot of the CSS editable from there. Downside is that, as the author says, sites can be slow. I think he recommends using WP-Supercache to offset this, but that may not be suitable for all content types.
