Custom Buttons are by far my favorite feature in the new Google Toolbar, which comes out of beta today. Clearly I’m not the only one, either — we have over 600 buttons in the gallery, with new buttons being added every day — and here are some some of my favorites, if you’d like to add them to your Toolbar. If you’re interested in making your own, it’s pretty easy. Just go to one of your favorite sites, right-click on the search box, and then click “Generate Custom Search.” You can find out how to add advanced features to your buttons here.
