[Pharo-dev] TilingWindowManager -- WorldManager? [Pharo3.0]

[H. Hirzel]

Hello

I installed TilingWindowManager through the
MetacelloConfigurationBrowser  in Pharo 3.0.

The class comment of TWMWorldManager says

    I provide an unlimited number of blank canvases on which to create...

    "Add a world:"
    WorldManager instance createOrSwitchToWorldNamed: 'JustAnotherWorld'.

    "Return to the default world:"
     WorldManager instance createOrSwitchToWorldNamed: 'Pharo'.


However the global WorldManager is not known anymore. What do I need
to use instead?

Thank you for the answer in advance
