By now it's only one order - random. So some wallpeper I never seen. Please, add ability to set change order. For example to: consequentially, random, shuffle(remember which wallpapers already shown, even after restart). Reproducible: Always
I too would like my wallpapers to not repeat until all wallpapers have been shown (Shuffle or Sequential), unlike random (the only choice) which has a habit of selecting the same wallpaper several times.
