I think it's important that Moodle is aware of different UX designs that suit secondary school teachers, so I thought I would drop a short note about a competitor in the Australian domestic market called StileApp.
StileApp is a content creation/Quiz creation tool that can be used to host a class of students. It doesn't have the power of Moodle in many areas, but it does make content creation easy using a lot of on screen Ajax calls when editing. When given the choice between Moodle and StileApp, many teachers are choosing StileApp.
It would be worth Moodle HQ taking a look at it in terms of UX design as it is a competitor.
