Modified filenames were highlighted with a different background and applying changes to all files was a simple CMD+S. You could use the keyboard's arrows to move around the filenames without extra clicks or bulky interfaces. With the files in this interface, you had your "standard" find/replace tools (CMD+F), as well as the ability to use REGEX. Imagine a text editor (such as TextEdit, Sublime Text, etc.) open to a document that simply lists all filenames, with each filename on a new line.

You would select the files you wish to work with, and their filenames would appear within what was essentially a huge textarea. Many years ago - when I was a Windows user - I had an application which made renaming files an amazingly simple experience.
