Feature description

Add an option to protect the Manage Hidden Icons settings item with a user-chosen password.

Why do you want this feature?

Currently anyone with access to the phone, including a smash-and-grab attacker, can long-press the background, bring up the menu, and select Manage Hidden Icons and see and use the apps that have been hidden. Users may want to password-restrict access to the hidden icons which might include banking apps, bitcoin wallets, or other apps with sensitive information, providing a welcome additional safety layer.

Additional information

It is true that all apps can be accessed via Android settings, but there are apps to password-protect access to settings. But adding such a password protector app to Fossify Launcher as a whole won't work, since the launcher would have to be password-unlocked all the time to use it. The best solution would, I think, be to add optional password protection to the Manage Hidden Icons menu item.

Would be very useful as a mean of parental control. It would also be nice to have an option to hide app hiding menu entry, so the user cannot hide any more apps. Obviously the setting should also be password protected, when the password is set. This way the child would not break the setup by accident.
