Upon activation, a new "Rename" column will be added to the Media Library window:

The plugin will look for file names that do not match the media or image title in the library. If there's a match, you'll see a green check mark symbol, otherwise an "Auto" button will be displayed allowing you to rename the file. More than that, the plugin will recommend you an ideal filename based on the title of the given media element:
