Aren't the tracks in the playlist window? That's where their allways been in
the cddax plugin. Just that now their are sorted in a "folder" for the cd.
The next/prev bug is probably just a tiny glitch because of the playlist
rework. It will be sorted out sooner or later.

Could be many things. Could just be that the interface doesn't catch up on
the update any more.

I could indeed do that, when updated libraries enter debian. I'm too lazy to
both compile the libraries and investigate the code.
