Comment 126 for bug 930148

Just giving my 2 cents in, i agree that for some users the launcher suddenly hiding would be confusing, but i say "Dodge active window" and "Dodge all windows" should still be available as options (selectable through ccsm, ubuntu tweak, what have you, for the poweruser) and just set the default to never hide. In this way we can avoid confusing users while still giving power of customization to people who know what dodge is and like its behaviour.
I honestly don't see any benefit from actually removing the dodge code from unity.
