This version provides new merge template slugs that can be used to provide navigational content similar to that found in a Web book. See the included ‘What’s New’ Help link for details.
This beta version is no longer available. Look for a later beta release or the most recent Mac App Store release.
Just that what I was looking for. Now, I can go steps further: Refining the namespaces (things rather than songs 
and templating/theming). Thanks a lot and greetings from Switzerland. You made my day.
Glad it is working for you! Thanks for the feedback! And fun to hear from a user in Switzerland!
Trying out now. All went well with the Dec. 5 build by the way.
The changes included in this beta can now be found in Version 11.0.0, available from the Mac App Store.
This Beta ran smoothly. I’m running V. 11 now. Thanks, Herb.
