Minor nitpick, and getting off-topic, but Apple's "Finder" is essentially the Mac OS interface program (the windows showing all your files, your Desktop, the Trash, search, etc. is all part of the Finder). What we're describing here is called "list view" on a Mac. As opposed to "icon view" and (in OS X) "column view". Steve P.S. -- to any OS X techies out there itching to point out inaccuracies in the above, I'm of course speaking in relatively broad terms here.
