How about writing a wrapper class with QProperties for all the
settings you want to store. This class internally uses QSettings for
writing them to persistent storage. You'll have to make it a singleton
though. The notifications can come from the usual property changed
signals.

This way you can also control which properties are read-only and which
ones can be changed.
