As long as I cannot get the full functionality to harbour I will publish "Forbidden Fruits" versions in OpenRepos: https://openrepos.net/content/cy8aer/podqast.

This version has rudimentary mpris support (Controls on start screen).

I have tried to do this with simple DBus but I do not know how to give functions and properties upper case names in QML DBus. And mpris defines upper case names. If there is someone who has an idea how to map qml names to upper case: please tell me how to do this.
