This second iteration is lacking most of the necessary fields to view, edit
or add a to-do item. These other fields and buttons were not written down, but
they are the same as in storyboard 1. This storyboard was intended to develop a
better understanding of the sorting functionality. Here, sorting on the main page
was refined and improved. Now each sort criteria (item priority, date due, group, date
entered) can have a sort priority established.
