Audacious

The options to control the way Audacious searches for cover images (which words to look for in the filenames, whether to perform a recursive search, etc.) are currently found by opening the Popup Information Settings dialog box from the Popup Information section of the Playlist preferences.

But the retrieval of cover images is not a feature of the popup information box only. Cover images are in effect retrieved and displayed in many places (the Info Bar, the Track Information dialog box, etc.) and are not necessarily related to the popup information.

A user wanting to fine-tune the retrieval of the cover images displayed in his Info Bar (for example) won't look at the 'Popup Information' settings. I think the most intuitive and appropriate place would be the Metadata section (see attached mockup).
