A nice functionality would be to secure the panel with a PIN. Also adding a button to start the screensaver without waiting a certain time. After activating the screensaver, a PIN must be entered to unlock it again. Very useful when there are small children at home 
For example, you could add a schedule when a specific pin lock is to work and when not.
@korzeniewski36 User permissions, available in 26.0 release, allow to protect dashboard with a PIN. There is no specific scheduling functionality, just a timeout for user permissions.
Please check it out, if that helps your use case.
