Use to love it. First  the GOOD. This app is the best wallpaper changer app that I have found. Cycle multiple images on regular intervals  blur and dim images to help see icons on launcher  rotates images if launcher can support it  and handles images of different sizes. Now the BAD  this app use to show the whole image and would adjust scrolling depending on the image size in landscape but now it won't go to the edges. Also the double tap feature is broken on Smart Launcher. Although I think this is the Launcher's fault.
