It seems Gnome lacks this useful feature.

Sad but true!

It also looks to me in general, Gnome (2.6) and its configuration concept
is a big mess. I recently used KDE a couple of times. Although KDE is a
heavy weight too, every customization I could think of was found at a place
of my first guess. Especially that missing feature below......

The overall performance of KDE was about the same or better for things of
daily business, and it has nice built-in gadgets like individual background
images per virtual desktop, rotating or persistent per desktop, if you prefer.

And finally the latest KMail has about the same features than Evolution's
e-mail part but is much faster and has a very good search functionality
(not that crappy "Find Now" of Evolution, Sorry!!)
