Once the plugin is loaded a new drawer appears at the right side of Mail's main window. If an e-mail is dragged to the drawer, a task is created that is linked to this email. Vice versa, when a task is double clicked, the associated email is opened. It is even possible for a task to retain links to multiple emails, so the whole context of a discussion can be attached to a task.
PIM-Mail can also support collaboration, since sending out tasks to others is as easy as starting the subject with "Todo:". For e-mails with these subjects, an associated task is automatically created.
In any case, once a task is marked as complete, an e-mail to the sender of the first linked e-mail is opened, to minimize the effort to notify him about the task being completed.
