We use local filter settings quite a bit in Poodll to allow user to specify a non default settings option for recorders and players at the course or activity level.
Its always been a bit hidden away though, so recently we use a more intuitive system. But for anyone using the local filter settings currently, the settings are not included in the backup and restore of the course or activity. I think there is nothing we can do at the plugin level to implement this. So I am not sure what they best way to deal with this. And actually I am not aware of any non-Poodll use of this feature either.
Is this a bug /new-feature for core Moodle? Or should this be done another way?
