Show Knowledge Base articles in support widget, rather than opening a new window

One of the best features of the widgets provided by competitors like UserVoice, Zendesk, and Groove is that they embed related/suggested knowledge base articles directly within the widget interface, rather than opening up the helpdesk site and article in a new window. This keeps users on your site and provides much better usability. I'd be much more inclined to adopt and recommend Freshdesk if the support widget worked like this.
