I know I'm reaching but can anyone see the possibility of being able to hide or lock one of your screens? I'm guessing this would have to be a feature in one of the home replacements.
So, let's just say that, hypothetically, you wanted to create a screen that contained personal content/apps. Then, when you wanted to show off your phone or hand it to someone else to use, you could either hide or lock that screen so they couldn't see it.
I know that's not a feature that's available now but does that sound like something that would technically be possible?
