The ZoomNavigator in Croquet looks kind of similar to the ZUI things
that are being explored at http://www.cs.umd.edu/hcil/piccolo/, or
http://www.cs.umd.edu/hcil/fisheyemenu/.  Are there any thoughts of
developing the ZoomNavigator into a more widespread menu system for
Croquet? Or Tweak?  Or Squeak?  This kind of navigation has some
advantages over other hierarchical menu systems, although for my 2
cents worth, removing the hierarchy and using one long list is more
worthwhile, as in the second link above.  Although how does
categorization play into this?
