you can do a subclass, installed as a plugin by amarok, then all
amarok applets would have to indicate X-KDE-Library=amarok_applet or
something like that in their desktop file, so they would all load the
same C++ applet subclass in place of the plain Applet, that one would
access the singleton

there is QQuickWidget that can be used to add qml views in widgets:
however is even more buggy than embedding a qquickWindow like that (it
has some bad architectural problems that are probably not solvable in
Qt5 lifetime), so you would end up using a qquickwindow anyways in the
end

I want now to try to add in my branch the possibility to set custom
data dirs, so you would install all your stuff in share/amarok instead
of share/plasma (then, whether have the shell private of amarok or of
a generic "applications specific" can't really decide yet)
