Hi a.m.,
I know this have been discussed several times like links below.

However, as we know the extension related pages of nopcommerce.com is still far away from perfect. The search feature you added in last year is a little bit shabby (without search box even on the extension home page, just a link). Also the categories of extension is fixed to those types like forever.
NC can only grow up to a better ECommerce platform when there is better third party solution and good extension. Really looking forward to seeing improvements like what we can find from magento connect:
