To me one of the biggest advantages of PBase over competitors (SmugMug, Zenofolio, etc.) is a clean, efficient and simple look without much of bells and wistles and unneeded ornamentation. That's the same site design approach that made Google and Yahoo so successful.
I'm all for for changing whatever is under the hood to make things more efficient and functional but for site face I really hope that with the new redesign you'll continue in the same simple vein.
