My wallpapers are stored on a location that is not always available at system start.
DF tries to load new wallpapers from there when I boot my computer but then doesn't find any wallpapers. It then switches to black backgrounds.
Could you add an option to keep the current wallpapers if all the sources (3 in my case) I have defined are not available or don't contain an image?
This way I wont have to manually force a wallpaper change after the sources have been mounted.
I'd love this feature too - really irritating to come back to my computer after resuming from sleep to find no wallpaper. Any chance it'll make it into v9?
