Check out SPToolBar
Caught a posting by Michael Greth on a new (at least I think it's new) release of SPToolBar, a tool put together by James Milne. James is the gent responsible for his only SPSkin tool that lets you build your CSS files for SharePoint Portal Server and Windows SharePoint Services sites. SPToolBar is a nice Web Part that provides some features that you can add to your otherwise bland pages like creating a printer friendly version of the page, sending the page as an email message, adding to your Favorites, and other goodness. You can download it directly here. Also check out James' other projects on his home page as they look pretty interesting!
