Let's say I have three folders each with a different category of wallpapers in them. I add all three folders to each of my monitors in DF. When DF randomly selects wallpapers, it would select a wallpaper from the same folder for each monitor.

So in essence it would be this:
You have folder A, B, and C.
DF chooses to randomly select a wallpaper from folder B for monitor 1, monitor 2 and 3 follow suite and randomly select a wallpaper from folder B as well.

This would be a great feature to have for theme matching wallpapers on each monitor.

Well I'm hoping it would be added as a feature, rather than done with a workaround.

Thanks, I appreciate it.
