While in teacher mode, the set of currently checked out books can be reviewed by tapping on the Checkouts tab.
This causes the set of currently checked out books to be displayed, in order of checkout, with the oldest at the top.
For each checked out book, the book title, the student's name, and the checkout date is displayed.
Normally, students check in books by scanning them, but you can manually check in any of the books in this list by swiping left to reveal a Check In button.
