Make list of supported filetypes more user-friendly
Forwarding the feedback of a user:
While looking at it, I thought: I'm not really sure how much help the list of supported formats is to the average user: Probably, the list should be sorted alphabetically. Besides, just listing file extensions like '.odt' instead of 'application/vnd.openxmlformats-officedocument.presentationml.presentation' would probably be better understandable.
