Let me start by saying I like Canvas. I am hoping for more testing options, but that will eventually come.
I can tell you the number one thing that drives faculty nuts is the automatic hyperlinks on the students' "to-do" assignment list. Canvas has made it so easy for students to simply by-pass any curriculum building that has been done on pages leading to the assignment or discussion post.
This seriously has to stop. This is so frustrating, for it doesn't matter how engaging I make pages when students just jump to the assignment.
The answer is to simply remove the hyperlink to the assignment in the "to-do" list.
