I was watching MKBHD and he mentions his "favourite new software feature," Screens.
Well, not Screens but Samsung has built it in.
To be honest I expected Google to do it, I even thought there would be a new/actual API to do it in Android 8.
Anyway all this means it that I had a good idea, I did have a TODO list for Screens but lets be honest, I was never going to do them.
