Do you have a favorite text style that you would like to send emails? And Sick of changing it to your favorite style all the time? Now in GMail you can default it to a specific text style for all the messages.
If you like to use a specific text style for your messages, you've had to change the font every time you're about to start typing out an email. Now, you can turn on default text styling from the Labs tab, then go to Settings and set your preferences just once.
In future I would like to see this in the signature as well.
