I love the use of Due dates to organize Next Actions rather than just looking through a list of 50+ and choosing. I use the Today view every day.
I use a CRM at work and love the fact I can look at future dates (next week) and make sure I haven’t jammed in too much to do AND be able to deal with ad hoc items.
It would be great to be able to view JUST the tasks due on a certain date, or at least being able to sort Next actions by due dates in chronological order.
