What is Ghost Mode of Superuser Elite? Superuser Elite (paid) provides a premium-exclusive feature: Ghost Mode!

What is it?
As I haven't purchased it, I don't have option to test it..
The Superuser website explains it as such:


  Ghost mode – Hide Superuser from your app tray and home screen. With
  ghost mode activated, the only way to launch it is by dialing a secret
  code into the dialer. The default secret code is *#*#787378737#*#*,
  but it can be set to whatever you want. Note that this feature will
  probably be disabled if your device does not have a dialer (tablets
  specifically).
