A request: Ideally the app should include a way to customize your due date view so you could have a single veiw of what's overdue, what's due today, due tomorrow, etc. Should be able to tailor to your preference.
A less preferable feature but still better than existing app would be to show overdue tasks and due today tasks in a single view. Whether this would just rollover overdue tasks or show them as a different category wouldn't matter too much.
