Ok, since this is pretty similar to my previous suggestion
some more explanation would be needed. First - the idea
is pretty different here. It's not about plugin being
unique or not, it's about cheching for certain conditions
which should be fulfilled.

Take for example the xkb plugin. If I run a Xvnc server
and connect to the server there is no XKB extension
available
(Xvnc does not implement XKB). So the xkb plugin could not
function at all. As a result the panel currently crashes.
This is firstly plugin's fault and I'm working on a rewrite
of this plugin which sould handle such situations more
gracefully. I also know that with the new out-of-process
plugins a crash in one plugin should not crash the whole
panel. But nevertheless I think such API would be of help
in making XFCE more user-oriented desktop.

I think having such a function is a good thing, since the
plugin writers can use it to check for certain conditions
needed to run their plugins. If the plugin doesn't depend
on any such conditions or the plugin writer doesn't want to
implement it the simpliest thing is to "return TRUE;". I
think it wouldn't be hard to implement this from the panel
side. It might slow the add new item dialog (or whatever
it will become in the future), but this is pretty rarely
performed task.

Hey, that's just my opinion. :-)
It's up to you, I just think such an API would help in
creating a more "usable" desktop environment.

Best regards,
Alexander
