I knew Good Lock was a thing, but never had I gotten around to trying it before today. After a ten minutes playing with it, honestly I still didn't really get it... waiting for something exciting to happen.
But then I started playing around with the Quick Panel and Theme Park, and several things that really annoyed me about modern devices (information overload, having a watch/tablet/phone that all show me the same repetitive UI labels) are now under my control to either customise or make disappear!
Thank you to the Good Lock team! My whole Samsung setup just got that much more immersive.
