+## Improvements
+
+If I were doing this again and had more time than I did for this prototype, I'd
+probably investigate a few more things.
+
+ - Instead of having settings/object/action-name/action-target/etc I would abstract
+   something to read/write values which can notify when there are changes. Something
+   akin to a bi-directional GtkExpression.
+ - I'd probably look for ways to use widgets natively within the XML file and create
+   them on demand. That becomes problematic when doing bindings, but is still possible
+   if we injected the right state into a new GtkBuilder XML starting from somesort
+   of synthetic "child" element handled by the GtkBuildableIface.
