Gmail Tasks has been moved from the labs section of Gmail to the main account a while ago. It offers basic task list management in the Gmail interface. Gmail users can for instance create multiple task lists, add notes and due dates or print them for offline use. Some Gmail users however requested a way to transfer the task list electronically which is what the Gmail team has now implemented.
Gmail Tasks users can now easily send a task list by email which might be interesting for some users who want to notify another person of their task schedule. Sending out tasks by email will add all tasks in list format to a new email in Gmail. The email will also list the name of the task list. Notes and due dates on the other hand are not added to the email.

A question about the benefit of this method opposed to simply writing the tasks down in an email will surely come up. It would have made sense if notes and due dates were included in the Gmail tasks export but they are not. It might therefor be faster in some situations at least to write down the tasks manually instead of using the Gmail Tasks menu to export them. Some users who spend most of their day in Gmail might appreciate the new feature on the other hand.
