I have recently released my sixth CodePlex project (list of all my CodePlex projects), titled SharePoint WebPartSlices.
To all the jQuery fans - Sorry, no jQuery this time! SharePoint WebPartSlices is a server-side solution that allows users to transform all Web Parts on a page into IE8 Web Slices simply by adding the webslices=1 querystring parameter to the url of the page containing the web parts to be transformed, basically allowing you to add web parts to your IE8 Favorites Bar.
Voilà - No need to navigate to the original page to see the updated Web Part.
Installation consists of a WSP deployment + Feature activation only.
