Something that stroke me is that the first thing we "see" in a lesson created with the lesson template is the pictures of the authors (even before we see the title, the lesson description and overview). I don't want to diminish the work of content providers, but the order in which the sub-sessions appear seems odd to me. Currently they are: Title, Authors, Lesson Overview, Contributors, Citing this lesson, Setup.

The authors are less informative about the resource, then the description... and the contributors only appear after the description (they should appear together - right below - the authors).

I suggest to change this order to:
Title, Lesson Overview, Setup, Authors, Contributors, Citing this lesson.
