So I really like the Chrome bookmarks toolbar. Between Safari5, Firefox, and Chrome, it's the only bookmarks toolbar that shows the favicon — and gives me a nice way of storing frequently used bookmarks. I bookmark a site using CMD-D, save it to my bookmarks toolbar, and completely remove the "name" of the site.
That makes a nice little icon on my bookmarks toolbar:
Power tip: Use CMD-SHIFT-B to quickly toggle turning your bookmarks toolbar off and on. Nice for getting a little extra vertical space when you need it.
