Finder Smart Folder - Seeing file size in OS X 10.5

"A list view, or list part of cover-flow, in a smart folder will show the name, kind, and last opened date. It does not seem to allow you to change these columns, and there are no view options (command-j) for a smart folder.

It might console you slightly to see that if you view the files in icon view, certain types, like dmgs will show their size in blue, and movies will show their running-time.

I would recommend just getting a listing with sizes from the terminal with ls or du but I'm not certain that the smart-folders look like directories on the unix side of things."
