For me: lower prio. Not sure if this deserves their own html page. OR we find a way to to this in rst way.so we can reuse this format for this kind of info/gallery lists. same with #19

The link in the report are dead and should be replaced by http://geonode.org/user_features/ and http://geonode.org/dev_features/ Not sure how or what is expected though
