Once again, Google’s added another nice update to the technically still-in-beta Gmail.

While this won’t be doing a whole lot functionally, Google has added themes to Gmail, allowing you to customize your entire interface in one of about 30 themes. They look nice, and add a little coolness to the normally bland Gmail interface, similar to iGoogle themes. Also, it seems that, like with iGoogle, they’ll be adding more themes over time.

Useful? Not really. Fun and Cool? Yes. To apply, just go to your settings, and click on the new theme tab. Even if you dont customize btw, Google has updated the entire Gmail interface slightly. That’s all folks.
