This idea has been developed and deployed to Canvas
Currently I grade by using a rubric and/or making a comment on the bottom right of the page, going back up the page to fill in or verify the grade, and then have to move my cursor up to the top left of the page to click the arrow to get to the next student. I would like a "next" button right next to the grade that will take me to the next student. There should be a similar button at the bottom of the comment box, i.e. "submit comment and next". And pleeeeeease make the type bigger in the comment box. Reduce clicks and mousing.
