It would be helpful to have the matter number and client name in the notifications. Right now it just shows me the title of the task, but it would be helpful to know which client/matter it corresponds to so I can easily tell if it has been completed and then I can mark it as read.

Also, after a task is completed, I think the notifications should go away for the reminder and for the underlying task. That way the notification icon with the number of outstanding notifications will go down as tasks are completed.
