In Moodle, you can choose to hide a course from participants which is great when getting the course all set up and ready before it launches.
However, if you have a huge number of courses, changing all these from 'Hide' to 'Show' means spamming the middle click button to open all in one window then going to the next page and continuing the process... Very time consuming.
A way to select all courses (or certain courses) and choosing to "Show/Hide All Courses" via a button would be rather lovely! And would also cause my finger to be a bit happier, too.
