I do not like a SINGLE thing about the new layout, and aside from the people with vision problems, I cannot comprehend how anyone could like a single thing about this, unless they're masochistic.

Please implement CCS options so that we can choose our layout, without the loss of category functionality that you plan to implement.  That way, those of us who liked the old layout can choose that, and people can also choose a layout that is optimized for their monitor or device.  If you are not skilled enough to do this, then I demand you hire someone that is-- yes, I, as a customer, and on behalf of all of your customers and vendors, absolutely DEMAND it, and justly so.

Also, make the sale font yellow, for crying out loud.  I have the brightness and contrast at max and it's still difficult to read.

Otherwise, I demand you return the layout to what it was before, including the frame at the left on the vendor page.
