How does work invoking LaunchPad when you are in a Fullscreen App?

[djrod]

For instance, what happens if I am in FullScreen Safari and I do the 4 finger pitch to call Launchpad?

Does it goes to an empty Desktop to show the dock + Launchpad or does it just show the Apps icon in front of the FullScreen App?

It goes to the desktop.
