Still working on this week ToDo list… Most of the work is needed to create a handbook style course management of content. By the end of the week, I want to be done and ready to start working on the quizzes/tests component (the most tricky one).

An example of Course handbook main page will look like this:

~ Home
+ A course subpage closed
+ Another one closed
|- A course sub-subpage opened
| + Another one closed
|
- Last one

The tree will be also searchable, and every subpage will have previous/next navigation.
This issue is one of the important features for learn.wordpress.org
