A useful GUI?

From: Paul Murrell

From: Frank E Harrell Jr
I saw an ad in the July 2001 Amstat News for a complex sample
survey analysis package called Wesvar.  The package has
what appears to be a useful feature called a "Workbook"
by which the user navigates analysis output.  This is a
hierarchical tree in which the user may click on a part
of the analysis (table, regression fit, descriptive stats,
etc.) so as to go directly to that output.  Recent versions
of SAS have something similar.  In SAS the title of a
graphic may be what appears in the navigation tree, and
clicking on that entry will replay the appropriate graph.

Has anyone had experience with such GUIs and would comment
on productivity or documentation benefits?  I wonder
what would be the most platform-independent way to
implement such a feature, e.g., dynamic html, if it is
useful to statisticians.

Actually, I'm in the process of looking at building something of this
nature.  Comments and suggestions about design principles, as well as tools
would be appreciated.
