This is a handy feature using Google Calendar. When you mark a task as “Done” in SmartTime, we place an “(x)” in front of it the next time you synchronize your tasks with Google Calendar. This allows you to create a handy archive of all of your completed tasks. Just move to Agenda View in your Google Calendar, type “(x)” in the search field, and here is what you get. View, Manage, even Print or Export!
