It is a real Kirigami drawer.
But in order to use this, I changed ElisaMainWindow.qml from a standard Qt ApplicationWindow to a Kirigami.ApplicationWindow.
That might have side effects that I am not aware of :/

I'm having a look at this if everyone is ok.
I started following the kirigami drawer idea using the states browsingViewsNoPlaylist and browsingViews defined in ContentView.qml.
When in the browsingViews state, keep the current layout.
When in browsingViewsNoPlaylist state, currently the playlist disappears and is no longer visible, I juste added a drawer that is enabled only in this state.
I made a quick video to show what it currently looks like (attachment).
If this direction is ok for everyone, I will continue working on this.

Thanks,
