I already know the relevant part (mimetypes) of those .desktop files, and am
aware that I can remove mimetypes from the relevant entries to make them
disappear from the "open with" list.

The problem is that some applications (Libre office writer, geany) appear in
such "open with" list even though they do not show to support the mimetype
of the file.   I do not see any thing in that regard.

Also, the main problem, the word "sort" appears exactly once in that
document (in the second paragraph), and gives no information how to
influence the order of items in a "open with" list.

The word "mime" appears twice, once in a "its supposed to handle this too"
line but with no further information, and once in a link - which (rather
tersely) mentions how you create hem, but nothing about managing them.

Thanks for trying though.

Regards,
Rudy Wieser
