I think it's clear that the different GUIs should expose the information 
in different ways.  The OSX Gui shows the list of all vignettes in a 
very nice multi-column display, including descriptions, but as far as I 
can see it will always show all vignettes, not just those in attached 
packages, and it doesn't allow the user to drill down through the 
package list to the list of vignettes in just one package (other than by 
scrolling through the whole list of vignettes, which are sorted 
alphabetically by vignette name within package name).  If a user has all 
of CRAN installed, your design would be easier to use, but I wouldn't 
suggest that OSX should adopt it:  they should just steal the good parts 
of it.

I'd like to have a multi-column selection list in the Windows GUI, but I 
don't think we should wait for me or someone else to program that before 
including this improvement.  It will be easy to change the look of the 
list later if we want to do that.
