I wonder if it would be possible to be able to pick certain apps, while in visitor mode, that you would be unable to access without your password. I ask this because in the current visitor mode, it works great for the dialer and the messaging, but it doesn't work for Google Voice where messages and voice messages come in as well. Also if people use instant messaging that could be a problem too. So, to add a option to pick certain apps that would need a password to open during visitor mode would be awesome.
