This is a different issue than a recent post of mine regarding downloading student solutions.
When I view Learner Solutions in Canvas+Grader there's no identification of which student submitted which solution. In other words it's not at all clear to me how (if?) I can look at the submission for a particular student of my choosing. The "Selected Learner" tab within the page lets me select a student but apparently not by student name.
So - how can I, for a given student, look at (for example) the most recent code that the student has submitted? If a student mails me and asks me to look at the code they submitted, how can I do this basic thing?
