Your info is a big help and I trust it will help others. Off I go to consider some terse edits, plus add some cross link. Sounds like you went to logical places.
I am still struggling with the universal change in Moodle to "Update this Activity" (Lesson in this case). I still think of them as "Update settings". Update sounds like refresh to me. Oh well, I don't create much MoodleSpeak only translate it
