Add the Option to Hide Apps and Local Files.
We want to be able to hide apps that we don't want a random friend running. Require the pin to toggle between showing hidden apps and files makes sense to do both actions with one input because likely you would be using both at that time. Re-enabling wouldn't require the pin again, and would automatically be hidden again if the headset is turned off without manually re-enabling.
Also add a way to remove demos or any app completely so that the library doesn't get full of junk we don't want to see anymore. I mean sure being able to hide them would fix that too I guess but would still see them when unhidden again.
