Having recent files support might be nice, but otherwise we're pretty
good, with Thunar adding support for various file management
standards.

I'm going to try to have a GMarkup based recent files implementation
up by the September freeze, assuming all goes well, but it never does.
And it really strikes me as more libexo than anything eles

We've had some users complain about not labeling our .desktop files
for settings as being Xfce specific. One guy kept trying to figure out
how to make the Window Manager configuration option in the menu open
up a config dialog for Metacity

Perhaps you should collaborate with Benny. Is it possible or a good
idea to make desktop handling a gmodule or similar runtime loadable
component, so that they can code share? Might also drop some tech
support issues trying to figure out whether Xffm, Thunar, or Xfdesktop
are manageing the background, if they share a codebase

xfce-terminal packaged it's own plugin for MCS IIRC, and we are a
highly modular system. Bundling the plugins with it seems kinda
foolish, to me. Maybe I'm wrong.

Then I'll write it. I can't meet my code promises as often, but I
think I have demonstrated at least a minimal ability to write.

There. Something decided. What do I need to cover?
