This one (for the )?
The trouble is it has no way of displaying a menuitem conditionally.
The current implementation for UCA involves a file
~/.config/Thunar/uca.xml. This has <pattern></pattern> for each action,
so that thunar knows when to display it. There's no equivalent of this
in the desktop menu spec (because it was never intended to be triggered
on a file).
Also the Desktop Menu spec states the location the .desktop files should
be kept: we can't store ours there or they'll mess up the real desktop menu.

That specification for the desktop menu includes caching to an XML file.

Using .desktop files might be a good idea, but for it to be widely
adopted the layout of the file (locations etc) would have to be made a
standard by the freedesktop.org. That's not easy to do. You'd need a
standard for "Conditional Right-click Menus". It could be very similar
to the Desktop Menu spec except for:
1. different file locations (e.g. /usr/share/applications-conditional
and another one under ~/.)
2. something in the .desktop file to specify when the menuitem is to be
More exceptions might come up, especially in discussion with other
file-managers who'll have different needs.
