This gadget for the personalized homepage has been around for a while, but now it looks better and has new features.
The purpose of the gadget is to let you access your bookmarks. As you probably now, Google Bookmarks is a service that stores private bookmarks and could be used in connection with Google Toolbar or other extensions.
The gadget lets you restrict the list of bookmarks to a certain label. It's also easy to edit bookmarks or to manually add bookmarks. The only missing feature is search.
