I decided that it was time to start keeping track of what missing functionality in Magento is most wanted. I created a new page (which you should see in the navigation under the header of the site) to start keeping track.
Check out the magento functionality wish list page and post a comment with your most desired functionality requests. I’ll keep a tally and update the table accordingly. It should be interesting to see what makes it to the top of the list. If enough of you get involved, this could end up being a good resource for module developers, and perhaps maybe even Magento themselves.
