Customize Google Toolbar with Buttons

The Google Toolbar, which is now out of beta, has incorporated an easy way to add buttons/functionality. There are many buttons that come with the Toolbar. However, others are creating buttons and providing them for you to use. To add a button from the Gallery, just click on "Add to Toolbar." You can add a button that:

• checks the weather (of course)
• checks blogs
• buy movie tickets
• search Answers.com
• find reviews

There are many more! [from Official Google Blog]
