I update admin info. Yes, I want to take most recent courses from all sub-categories of the selected root category. For example, I have 6 courses in 3 categories:
category 1: id=1, id=4, id=5
category 2: id=2, id=3
category 3: id=6
If I want to display 3 most recent courses, module must to show me courses id=6, id=5, id=4. And it would be great if this selection allows language of course, because on my multilanguage site every course has a correspondent clone (this problem will be automatically resolved if the option allows to select several categories, not one as now).
Thanks)
