[Product-Developers] creating a chronological folder listing

[David Hostetler]

Thanks Gilles.  I will look into that.

For the time being, I just added a new script to my theme product that
mimics getFolderContents(), but does the date sorting that I described, and
made a corresponding template to leverage it (and do some custom
formatting).  The only downside is that I can't readily just apply this to
collection objects, since they have their own query implementation.  I'm
still thinking about how to handle things for collections.
