I've been through the beta in detail. Designed a new layout, set up the 800,1024,fluid variant files to correctly display at those resolutions and it still looks "reasonable" at 1280x1024, if I can do that, anyone with an html book in hand can do the same.
Nice job on the theme scheme Jamie.
Issue:
When editing a product for the first time, I edited the thumbnail default settings. When closing the "edit thumbnail defaults" window I was returned to the product list instead of back to the product page I was working on. The work on the product to that point was lost.
