When the page count of a lesson is uneven, the second last site is displayed twice. Once on the right side when on the second last page of the lesson and a second time on the left when on the last lesson page. This is both irritating and serves no purpose and should therefore be fixed. Lessons with uneven page count should have the last page displayed on the left when at the end of the lesson, with the right side beeing empty, just as it is in every book.
