Google search results blocker

It works similarly to Google Chrome's Personal Blocklist extension. You can remove google search results on a per hostname/wildcard basis. Eg, don't like recipes from www.marlenes-cookbook.com? Simply click the 'block' link in the Google search results and you'll never see her in the search results again! To unblock/export blocked hosts, open the Opera 'manage extensions' screen, and click the preferences button.
