Make the type of a document a necessary field
Make at least the subject and the type of the document necessary to avoid wrongly assigned documents, as at the moment only the title is necessary to upload a document. Going even further, it would be amazing if exams would also be sorted by the type (Spring, Autumn), so that the navigation really gets excellent.
This is dependent on the backend API Issue https://github.com/amiv-eth/amivapi/issues/422.
