9 December 2008 @ 8:58Quick Tasks List in Gmail
You can now add a Tasks List to Gmail. Go to Settings > Labs > Tasks > click Enable or just click here. In the Tasks window, simply click in an empty area of the window and start typing, then hit return to save you new task. You can even apply a task to an email by checking an email, and then under the More Actions menu, click Add to Tasks. This new feature should prove to be immensely useful.
