Last week, Gmail team announced gadget support in Gmail Labs that offer integration with Docs and Google Calendar. To complement this features, Remember The Milk team has released a new Gmail gadget that can be added to the left nav of any Gmail account, giving convenient access to your tasks alongside your email. The gadget allows you to review your upcoming tasks for the week including any overdue, add new tasks and edit existing ones, easily complete and postpone tasks, and customise the display (show tasks from a particular list or Smart List, and optionally show tasks with no due date).
The gadget works across all browsers, and doesn't need to be installed in each browser where you use Gmail. It’s one time installation into your Gmail account.
