This is a pet peeve of mine, but it's also an easy UI toggle. Don't get me wrong, I enjoy how much effort goes into the Home page tab of my courses; however, for all of my courses, the most pertinent tab is the Modules tab.
Right now, I click on my course, (load), the Home page tab opens and I click on Modules, (load), and then I can finally see my assignments and due dates instead of the syllabus/opening remarks. I'd like the ability to choose which tab the course opens first. I know the professor-view can do it; the same function just needs the permission added to the student-view with a select amount of options.
