Hello Hugo,
Thank you for the tip. However, I am not a Moodle admin, and our school is very strict when selecting plugins. Also, this suggested plugin only handles indentation, deletion, hiding, showing, and moving of multiple activities. It does not address selecting multiple filter criteria.
Something as usefull as multiple select should be in the core of Moodle. Available without plugins IMHO.
Hopefully, by making suggestions here, they get picked up by the awesome team behind Moodle. Because I really like Moodle. It is by far the best LMS available. But when working with it daily, you sometimes get the feeling of it being the worst LMS, with the exception of all others
