Hello Florian,

Some time ago I asked about chapter support in Musepack files and then you suggested to display them as "virtual tracks".  
I think this is a brilliant idea, because it can be applied to (almost) all file types.  
Currently I use Musepack chapters for conceptual and live albums that usually have subtracks.  
Both players that I use (Foobar and MusicBee) works fine (with some slight difference) with this native feature of the format.  
However, editing is almost impossible, once the chapters are embedded during encoding.  
I wanted to try mp4 chapters support, however I still cannot find a proper way to include chapters to mp4 (m4a).  
About ogg, although it seems quite easy to make the chapter tags ([ogg chapter extension](https://wiki.xiph.org/Chapter_Extension)), there is no player that supports them except VLC (partly, only display chapters, but cannot jump to a subtrack).  
Loseless formats (flac, maybe others) can have embedded cue sheets, but again, inline editing is hard or non trivial.  
So, I still that it would be a very useful extension if mp3tag can support natively display and editing of chapters and cue sheets as "virtual tracks".
