Can you designate more than one file name, so that the first one found is imported? For example: folder.jpg;folder.png;cover.jpg;cover.png. I think I may be able to do this within an Action Group by designating each one in a separate action, but that seems very awkward.
Can wildcards or regexes be used? For example: (folder|cover).(jpg|png|gif)
Is there a way to suppress the warning message if no artwork file exists?
Is there any way to make the action conditional, so that covers might only be imported into MP3 files, but not FLAC files?
