I really think Opera should allow any website to be pinned to the GX Sidebar as it would allow for easy quick access without the need to go to the homepage, search for it or to type the URL. This also exists as a feature of the favorites bar but that looks like an obstruction, this would be a better application, and not much of a hassle, as implementing it, not as a pop-out, but a hyperlink to a full tab would be quite simple.
