[kde-linux] In KDE4, to set a different background for each of the multiple desktops

I'm confused at what you are calling shower curtains??

I run Suse 11.2.
I think what you are calling shower curtains are folder views. ie a
plasmoid (widget) that shows a view into a directory. If so just click
the cashew at the top right select unlock now you should see a tool bar
at the side of the widget. there you can move rotate, resize, configure
or remove the widget.

You can add widgets including folder views by selecting add from the
cashew's menu once the it is unlocked.Locking locks the widgets in
place. You can bring the widgets to the foreground by the show dashboard

I find KDE 4 much much better and more flexibly then 3.5. Once I found
the cashew all else was pretty intuitive just read the selections on the
menus and setup screens. You can have a activity set up to do program
development on one graphics on another multimedia on another etc.
switching "desktops" is actually just switching activities. In 3.5 the
desktop was the same for all "desktops" just different backgrounds. With
KDE 4.x each "desktop" can be unique for it's activity.

My 2 cents
