Is it possible to create a new Google Tasks entry from an email in Gmail?
Use case: create a reminder/task to respond to an email on a certain day.
There is a "More Actions" button above each email with an option to "Add to tasks". This then adds the email to your list of tasks which appears in the bottom right of your screen. Clicking on the small arrow to the right of the task allows you to edit the options and attributes assigned to the task, for example to set a reminder or additional notes about the task.
