There is a powerful but little known Gmail feature that lives in Labs called “Add any gadget by URL.” Once you turn it on, you can add iGoogle gadgets (or any gadget specified by an .xml file) to the side of your Gmail account. While most of these gadgets are built by third-parties and not owned or maintained by Google, they can be super handy.
To install any of these gadgets, follow those steps:
1) From your Gmail account, go to the Labs tab of Gmail Settings.
2) Look for the Lab “Add any gadget by URL.” Enable it, then click “Save changes.”
3) Go to the new “Gadgets” tab under “Settings” and add the relevant .xml address.
Here’s a list of a ten I’ve found worth trying out:
Wikipedia
Look for a specific query right from Gmail.
