I don't see the point. I haven't used it, but the site describes it as "adding Print and New Tab buttons to the Safari interface". That's as simple as Cmd-P and Cmd-T. If you're browsing a Mac rumors site, you're sure to be an avid Mac user. If so, then you've most likely learned those shortcuts. I don't see why you wouldn't. If not, then do yourself a favor and start learning key commands, especially the most common ones. They make life a lot easier, without having to download special utilities to do it for you.
