Since Smalltalk is such a good language for code reuse, I have been
wondering whether there libraries of useful classes that the Smalltalk
community shares with each other?  We are just getting started on a
project in which we will use smalltalk and would prefer not to have to
build everything from scratch.

To give you an example of what I have in mind, our project plans to use
Smalltalk to build a user-friendly front-end to environments, e.g., a
replacement for the C-shell (i.e., a new to Unix front end).  One of our
plans is to have a window in which the file system structure is
displayed as a tree (really a directed graph) of directories.  Clicking
on a node will cause a subwindow to pop up in which the files at that
node are displayed.  It would be nice if instead of building the MVC for
the tree browser ourselves we could make use of one already built.

Any suggestions?  (Note this is *not* same as the Smalltalk browser.  We
want to build an actual visual image with edges and labelled nodes.)
