I want to sell WP templates and plugins. I want to setup demo site like woothemes.com
When check demo site, they have top panel to change theme. Where do I get this top panel? It looks like this http://demo.woothemes.com/?name=editorial
And I want to sell plugin too, so client is allowed to login to WP admin panel too view fuctions...etc. But I just want client to see some part of WP admin panel, they cant download or copy theme, plugin from demo site. So which plugin that you recomend for me to setup demo site?
