Ferkinhell. I've already looked at Wallpaper several times, by searching for files containing the 'graphic-shader-texture', but I couldn't make it work when applied to the app launcher and so assumed it was something else. To me, 'Wallpaper' is more suggestive of actual wallpaper, a colour, a picture, not a translucent texture, but hey, once again, you are right - thanks for your one-time limited offer of help, I feel privileged!
