Currently, when a student makes a comment on his/her submission, the teacher will receive a message for that comment via a daily/weekly digest email.
However, in the teacher's mailbox, only the message saying that the student made the comment is shown, no real comment is displayed. The teacher has to click on the link "Click to view", login to Canvas (if he has not logged in yet), and go to the page that has the comment. This approach will take a lot of time if the course has many students.

It would be convenient if Canvas can display the students' submission comment text fully in the teachers' daily/weekly digest emails so that the teachers can just have a glance at all comments made by all the students without logging in to Canvas and deciding which one he/she will respond by clicking on the "Click to view" link.
