Another cover art management wish-list suggestion (unless I missed a feature in this ever-evolving toolkit):
In a view or tag dialog, allow editing of the field that contains the cover art image path+filename, and have MC automatically rename the file per the name change.
In other words, give the user the same ability to manually change cover art image files that already is available for media track files. One difference, it's probably not wise to allow moving -- keep the cover art file where it is, but allow filename editing.
The main reason for this is that many -- MANY in my case -- cover art images have goofy/long/wrong file names.
For instance, the image name assigned during ripping often is ultimately wrong. When the image is found and added by MC during Ripping, the image gets the track/album's "temp" names. But often these get tweaked by fixing up the tags, and/or renamed per Rename/Move dialog settings to give consistent structure to a library. Yet the cover art retains the old, now wrong, name.
The same happens with images that are imported, scanned, pasted, whatever -- cover art images end up with filenames that are mysterious, misleading, incomplete, very long, or that have unhelpful names that make manual image browsing and management a big challenge.
I know one "challenge" is that for an album, all the tracks might share a single cover art image file. It would be wonderful if MC was intelligent about renaming ONE track (or a set of selected tracks) in an album. Instead of renaming the common image, MC could create a copy with the new name. This simple (for the user) way to split one album images into two or more would then open the door to giving different tracks of an album different images as desired.
MC's development wizards know how to allow tag/field editing that updates the physical media file. How about allowing this for cover art files too?
