SEO friendly URLS would be a must..
Ajax shopping cart adder, like at http://www.shopmate.co.nz/demo/performance-parts.html
Template system so that can duplicate default, and edit it.
Cleaner faster loading backend, the drop down nav doesn't need that fading effect...
Spam protection on the contact us...
Other then that, it's very nice, and of course a couple of modules like, PayMate, Bank Deposit, and Cheque are needed.
I will be using this as soon as a couple of these things are done
THANKS SO MUCH GUYS
