What is really neat about this utility is the PrefPane that comes with it (downloadable from the same page), which allows to customize it in all possible ways (display hidden or invisible files, treat archives or packages as folders, etc.).
One great option is the possibility to treat files with resources in them as folders, too, and display (even copy in the clipboard) these resources (for instance, the TEXT in a text clipping), directly from the Finder.
[Editor's note: Make sure you download both the program and the settings file. One of the options I like in the settings panel is "Show package contents". With this selected, you can drill down into any application bundle through the contextual menu item. The download page mentions that the program will expire at the end of June, but does not mention whether there will be a new version or not.]
