You can have different wallpapers for each virtual desktop, but the content remains the same. My idea is to have a separate folder for each desktop, e.g

~/Desktop/.desktop1/
~/Desktop/.desktop2/
~/Desktop/.desktop3/
~/Desktop/.desktop4/

which content is displayed on the desktop. So you could have a primary desktop with lots of HDD/CD/DVD icons, a second one with some important applications and a third and fourth one with folders you need often for your work.

Of course you can also mess these all. This would be a good feature, for folks, who do some different kind of work, so they can have files for project1 on desktop \"Projekt1\" and files for Projekt foo on desktop \"Foo\".

No screenshot yet, but I hope it\'s clear, what I mean ;-)
