Someone else here suggested putting in "due on <foo>" headers to those views, much like the desktop app does. Makes the sorting more obvious, but sacrifices some screen real estate to do so. It would be a flat-list-with-headers, like we use in the nearby view. Would that work better for you?

One advantage of the current setup is that Project and Context hierarchies use left and right travel, while Overdue and Due Soon are just flat lists; there's less chance of confusing one mode for the other, since they don't behave the same.

If you haven't sent an email to the support ninjas, let them know if you want project hierarchy, context hierarchy, date hierarchy, the ability to use settings to choose any of them, or some other thing I'm not thinking of. :-)
