Currently, Lumio defaults to Teacher Pacing. Most of the time I want students to be able to access my Lumio files at their own pace. So I have to change to Student Pacing. And that doesn't seem to stick! Being able to chose which I want to default to would be great and save me (and my students) a great deal of pain. (This seems to be the case even with the student links, which is how my students access the pages.)
