Finally, Gmail users will be able to manage their to-do list. This feature was missing for a long time in Gmail(also in other web email clients like Yahoo! Mail and Hotmail). I usually manage my to-do list from desktop like most of the people with to-do.txt. But I think I will go for a while with Gmail’s to-do list. In Gmail it has been labeled as Tasks. The feature can be found in the Labs section of Settings link. After enabling this feature, it will appear in the left side of Gmail UI below Contacts.

The to-do list feature is also available in Google Calendar with the label Quick Add. But in near future I hope we would be able to see some additional features with to-do list like sharing the list with others and integrating them with other Google applications (esp. Google Calendar).
