The Lesson activity is an advanced but very powerful and versatile activity. It's one of my favourite Moodle activities and fortunately during 2015 it started to get a bit more attention. One area which would benefit from some 'housekeeping' is the settings: which could be default settings managed from a Site administration page, and which of these could be marked as "advanced" -meaning that, on an actual Lesson set up page in a course, you would have to click on "Show more" to see them. Stephen Bourget is working on this at the moment in MDL-52414 and it would be great if any of you who use the Lesson activity could comment with your views.
First Aid lesson, anyone....?
Or perhaps you would prefer to Start a Revolution!
