Indeed, that would make the code easier to extend. I keep a note on  
that and we can try to refactor that in the near future.

Right now, I have to be a bit careful. I did all kinds of experiments  
in the latest commits, that very likely will not all make it into the  
next release. I am also waiting for feedback for that matters (see my  
next mail).

Cheers,
Lukas
