This is a feature request for a minor WeBWorK improvement.
When I need to extend set dates for one user, I go to "Instructor Tools", select a user, and then click on "View/Edit all set dates for one user". This brings me to a page called "Sets assigned to [student-username]". It would be great if you could add to this page a link to act as "student-username". Clicking on that link, I could then easily check that I entered the new set closing dates for this student correctly.
It seems to me that this might be easily implemented, and it would save me quite a bit of time (because of the many extension requests I grant).
Note that there is an "act as" link on the page detailing the progress of a single student.
Thanks for considering this!
