Users just starting out with Mail will soon be able to access the Mail setup gadget. This gadget is customized for Google Apps and assists with actions like adding a profile picture, creating an email signature, and suggesting Labs such as Undo Send. The setup gadget is hidden once the user completes all actions, dismisses the gadget, or two weeks have passed, but it can be relaunched from Settings. The new Mail gadget is set to be released to the UMICH domain in the next 3 to 4 weeks.
