FIX wallpaper disappearing!
When trying to apply a new wallpaper, or re-apply a current wallpaper, it is disappearing/not appearing. This is extemely annoying, as I like to change wallpapers/themes as part of brainstorming. This is on the latest Mac version; haven't tested it yet on Windows version
I believe this has been fixed in 5.5, please let us know if you are still experiencing this.

I also like that the wallpapers are being considered part of the theme. This is much better, as the color scheme often needs to be tweaked for best results with a particular wallpaper. There's been a tremendous amount of work done on 'safe colors', with sensitivity to the variations of color-blindness. It would be great if the community could develop themes based on these principles, that we could share.
