When you have a bulky Moodle site with thousands of users in different countries, it can be really handy to have all the language versions of a particular subject on one course page.
The problem is that when using course completion by a selection of activities in such a course, you can not specify the required activities per language. As a consequence of which none of the users will have the course marked as completed.
Therefore I think it would be a really helpful addition to have multilanguage settings in course completion.
For instance to enable you to select the required activities per language. Maybe by having a column for each language that lists all the activities. (Dependent on using the restriction by language or so).
Or that you can select several activities with an "OR"-statement.
Required activity 1 = "Introduction_EN" OR "Introduction_FR" OR "Introduzione_IT"
I already posted a feature request over here: https://tracker.moodle.org/browse/MDL-72804

If you have ideas about how to achieve this in code then please add your comments.
