No, not every setting (that would not make sense). Some can though, for
instance some x11drv settings and dll overrides.

Well, the way it works is that you select the app you want to edit and
then change to other tabs. Yes, the UI for this is not the best.

Long term my plan was this:

* Remove usage of the PropertySheet API, and just use a standard win32
tab sheet
* Move the app/global ui into a nice header at the top of the window
that is always visible
* Fix up the instant apply vs explicit apply stuff to be more complete
* Complete all the settings.

App vs global editing *does* work, try changing it to an app specific
entry in the Apps tab then altering desktop mode. You should find you
can scope it to the app.
