Tips and Labs offered by google. People from all over create small applications to improve Gmail. These are available from the Labs section of Google and all you have to do is enable the ones you are interested in trying. We have put a few below that we think you might find useful.
Use Tasks as a handy to-do list.
Turn on Tasks in Labs and you'll see a "Tasks" link under the "Contacts" link on the left of your screen. Clicking "Tasks" will open the task list, where you can add new items directly, or you can convert emails into tasks by clicking the More Actions menu and selecting "Add to Tasks." If you add due dates to your tasks, they'll pop up on your calendar as well.
Avoid email gaffes with Undo Send.
Oops, hit "Send" too soon? Maybe you forgot to CC someone ? Give yourself a grace period of a few seconds to cancel sending, then edit your message before sending again. Turn it on in Labs.
Never forget an attachment again.
Turn on the Forgotten Attachment Detector in Labs, and you'll get an alert if you mentioned attaching a file but forgot to do so. This is a little temperamental and requires using the word "attaching", but we are hoping the developer will improve it over time.
See which messages were sent right to you.
"Personal level indicators" put arrows next to messages in your inbox so you can tell if an email was addressed to you directly. A single arrow (›) is for emails sent to both you and others and double arrows (») indicate emails sent just to you. Switch the "Personal level indicators" option to "Show indicators" under Settings to see them.
Make Gmail go where the internet doesn't.
With offline Gmail, you can access your mail and use Gmail just like you're used to, even when you're not connected to the internet. Any messages you send while offline will be placed in your outbox and automatically sent the next time Gmail detects a connection. Get started by turning on offline Gmail from the Labs tab under Settings.
Set up canned responses instead of typing the same reply over and over again.
If you find yourself typing the same reply multiple times, try turning on Canned Responses in Labs. Compose your reply once, save it, and easily use the same message later. If you want to be fully automated, you can even set up filters that automatically reply to specific messages with different canned responses.
