Multi-lists for Muzei app analytics for September 12

Want to let Muzei Live Wallpaper pick wallpapers from groups of pictures in your gallery, arbitrarily grouped across multiple folders? This is the right extension! Note This app is almost useless without Muzei Live Wallpaper. ■Known bugs • Crashes have been found on OnePlus One A0001 for unknown reason. Please file a problem report if you encounter a crash. ■Unimplemented functions • On-boarding tutorial. • Quick search lists by name. ■Limitations • Images will be lost from lists if you move or rename them using filers/galleries/whatever which lack the ability to maintain the gallery database consistency. • This app can't handle images outside the gallery database; namely images on the cloud storage services.
