It would be great to have the ability to change the default view of My To-Do List to all activities due today only, not those due on or before today (create a separate section for overdue activities).

In the future, it would also be great to see a list of all untouched TSOs/new leads in one place rather than sorted by campaign. Most of the time users won't realize they have a new lead unless they are expecting it or stumble upon it.
