happy to be playing with #GTK again! this time enhanced by libadwaita.

I always found the treeview APIs hard (things did improve along the way) but doing this stuff with #Rust holy shit. 😵‍💫

@hbons the ListView API *should* be easier to deal with than TreeView, even for bindings, since there are no cell renderers or tree model implementations. We need more demos/tutorials, though.
