User Story:: As a user, I want to know whether I can accidentally change the filetype or not so I can concentrate on the renaming instead of worrying about the file type.
Current Problems: Currently, the file type is far away outside of the field so it might not be clear how it connects to the file name.
Possible Solution: One way to improve the situation for the user is to insert the file ending in the title inout field but have it greyed out to show it's not editable.
