I have two Moodle sites (for two different schools). both are on v3.1.6. When grading assignments online there is a filter at the top right of the screen that lets you move between different students' submissions, jump to a specified user, or (most useful) filter the list to show assignments awaiting grading.
The problem is that this filter is there for one site, but not there on the other. Could anybody suggest any idea why this might be as it makes 'ghostwriting' marking of work much more time-consuming? (We have no custom code running so it must be down to some kind of setting somewhere).
