This extension loads up Dharmesh Patel's awesome web app for hacknews. You can find the source of the web app on https://github.com/premii/hn and can also visit http://hn.premii.com if you want to view in the web page instead of the browser sidebar.
This extensions relies on the sidebar, so try to view in an a version of Opera which supports the sidebar. I would suggest the latest version of 'Opera Developer'.
