Feature idea: Visibility checkboxes, for who can see it

[elimisteve]

Behind the scenes, Notes would encrypt the Pages using miniLock in such a way that only the intended recipients could read it.

Example visibility option checkboxes:

• [ ] Anyone who joins this folder later
• [ ] Amber
• [ ] Bob
• [ ] Jim
• [ ] Sally
• [X] Steve (me)
• [ ] Theresa

Checking any combination of those boxes that excludes the first option would mean using miniLock. But if the user wants any future people to be able to see that Page, then miniLock would stay out of it and there'd just be the one encryption layer that CrypTag always supplies -- NaCl symmetric crypto.
