Since mod_subsection becomes part of core with moodle 4.5 and is treated as an activity, I think it would be useful to have the activity completion settings available for subsections (e.g. completion by having completed all activies in the subsection, or by completing a summary quiz).
Is this already planned, or possible for admins on a moodle instance? Otherwise I suggest adding this feature for better overview of completed parts of the course, even when the subsection is collapsed.

This is my first post here, so please excuse any formal mistakes I did in posting this issue, (or even better correct me how to do it better, thanks!)
