I like the idea of turning the catalog into a view. I'd also like some kind of sorting framework established.

As for node theming I like the idea of being able to break away the attributes from the purchase button....as right now, they're some what connected. Other than that, I'm pretty happy with what I can do with the product styles. Perhaps a better looking default style would be nice (think various image gallery setups).

Looking forward to seeing wha tyou guys come up with.
