This is an issue in multiple reports. If I have carefully created a report to capture users in a particular group that have not completed a certain course, and I open one of those users and edit them, then I click save, I am sent back to the main user report. This is incredibly frustrating when I'm trying to edit multiple users, and I have to navigate back to that report after every single one.
I think if you edit a user/course, you should be sent to the same report you were previously on when you hit save and close out.
