I three question more:
1) How can I put a button in a course/class page to guests who are not registered that say “Register to take this course” and open the register link/pop up or something like that in the same place of “start course”. Because the last is only showing to registered users.
2) How can I redirect the button “mark as complete” to the next lesson, because is not the best user experience to have to click on the button and then click again to select the next lesson
3) When I uplaod a video in a lesson, when I’m watching the lesson and put my mouse over the video the scroll down is disabled. How can I continue scrolling down?
