The desktop wallpaper manager doesn't store anything. I originally set mine up so both monitors choose randomly from folders. Then, I chose to set a monitor to only one wallpaper. When I wanted to switch back, it forgot all of the folders I have chosen for that monitor. Please store this information, it's a huge pain to re-add folders each time.

Even better, create wallpaper profiles. By that, I mean let me save my current settings into a list of configurations. If I have a set of images, I'd like to be able to give that set a name and add it to a dropdown menu that I can come back to. That way I can save my random setup in one, and use the rest for different set pairs.

The profiles are coming. No exact version or date is known, but they are definatly something Jon is aiming for.
