On a tangent, the inability to set a preferred application for wildcard mime
types like text/* and image/* is a big pain point for me.

I open text files in a lot of different formats, and I'd like to be able 
to open
them all with the same editor, but adding an entry for every text/* 
entry that I
could ever possibly use to my mimeapps.list is quite a pain.
