Password protect and allow third apps

[spiritwarri0r]

Hi, I saw your project is really good and simple , minimalistic for the purpose of it. I like it :)

I suggest this features if is possible to add them.

1. Option to block it by password previosly configured in settings.

2. Option to add others apps to a whitelist so you can run it in front of it.

3. Combination to unlock for example:
   Press touch screen 20 times to show you a panel to introduce the password.

*The panel is without the keyboard , I heard have some incompatibilities when immersive mode is enabled, So i was thinking more like a panel with 1 to 9 digits incrusted as buttons to show after your press 20 times to unlock the device.

After you introduce your pin number and unlock it, you have access again to all options , settings, and all buttons works again, home, back, volume etc.

I know it's a bit difficult but is the only thing I see that is necessary on an app like this.

Regards,
