Woohoo, looks great.
I noticed only one thing: the main box which contains the icon view and
tree view is too small, IIRC there was some change in GTK3 regarding
default packing behaviour in GtkBox'es.

Attached is a trivial patch which sets the expand flag to the container
so it will look properly again.
Though I'm not sure if this is the best approach, I'm not really
familiar with GTK3.


Thanks for your work!

Regards,
Enrico
