By the way, here is a small detail that could be fixed in the interface. In Moodle teaching training workshops that I lead, every teacher immediately hits the button, "Create Multiple Questions", and to their confusion, a mass of random questions appears which have to be manually deleted. They assumed, like me, that was the right thing to do since they wanted to create a quiz with many questions.
Could we move that button to a less prominant position and change the wording to something like, "create random questions", with ??help circle nearby explaining this function (which I still don't understand)
