Please make comments displayed to students automatically as the default. I often forget to click it and wonder why students have not retaken a test, resubmitted an assignment, or fixed their work. The clicking "display to student" is an unnecessary and time consuming step. Possibly make that option as "Don't display to student"
Possibly this could be a course setting option where you have comments displayed automatically.
During remote learning, this is the easiest way to communicate with students because they can see it in their grade book. They respond very well to the feature.
Please save us from this extra click. :)
