The Participants page on Moodle 3.4 upwards has a multi-function search box allowing selection of roles, status, enrolment method, etc.
However, by default, Inactive enrolments are displayed in the Teacher view, and they have to manually select "Status: Active" in order to see only active students. It seems to me that this is a change from the previous behaviour. In Moodle 3.3 and prior versions, if an enrolment method is disabled, then the Teacher cannot see students enrolled by that method. I would consider this a bug.
Is there any way to configure "Status: Active" as a default filter on the Participants page? I've put this query on Enrolments as there doesn't seem to be a more suitable place.
