Some people like to store their discs as single file archives, with cue and cover data embedded in a single file along with the audio rip. It would be nice if mp3fs could present these archive flacs as though they were individual tracks for software/devices that are not able to handle single flacs with embedded cue files.
Can probably combine this with 3407871 (Cuesheet support).
This is something that probably won't happen soon, but it is an interesting idea for later. At about the same time as I address other requests for different file format support, I can look into this.
