Does Miui not have the android daydream feature? It's a very useful feature to use when your phone is docked or charging. One can show photos or time, when the phone is docked or charging. Also, the clock has an option to be displayed in super dim mode. This is very useful when you put your phone on charging at night and need to see the time without being blinded by the bright screen.
Would love to have it in Miui.
