Hi, I would like to darken whatever wallpaper used so that I can better see the icons on my desktop. I've searched around and it seems that it has been mentioned here once before but I don't think it was implemented.

Just the darken will do, but maybe do something similar to the android app Muzei?
So the wallpaper is normally blurred and darken, but on gesture/shortcut(maybe triple click) it will revert to its original form for a few seconds.

Thanks!
