Email is such a important part of our daily lives and having your email do what you would like is so important. With Gmail you can customize it with Labs. I know in previous threads we have talked about this before however there are new labs out there so you might want to check it out again. So if your are not familiar with Labs you can kinda think of them as apps for your Gmail.

At the top of your Gmail click on the green hourglass or if you don't have that then click on "Settings"
