Google promotes Google Bookmarks new interface, as part of Google Notebook, which is more responsive, and uses “infinite scrolling” to display the bookmarks and the notes can be formatted using a rich-text editor. Google Toolbar 5 (IE-only) lets you save the selected text from a page, which appears highlighted every time you visit the page. A similar interface can be accessed directly from Google Notebook if you click on “Unfiled bookmarks”.
