Instead of one big Files directory with all the PDF’s in there with their original names, create a hierarchy under Files with directories named according to DT folders, and the files in there, named with their current titles.
I’m frequently going to Finder to grab a file to use in other ways, and the Finder’s interface for one big pile of files is sub-par.
So, am I understanding you correctly, that if I rename a file in DT 2.0, the filename in the Finder will also change? Or are you talking about something different?
