- * Why is this class a QObject and not a QWidget, and why don't we add the
- * NavigationBar itself to the toolbar?
- * That was the original idea: make a NavBar class, friend it from MainWindow
- * to gain access to the config, but there's a couple of issues:
- * - adding QToolButtons to a widget that's inside a toolbar makes the buttons
- * look absolutely hideous: they're smaller and have a border for some reason
- * - if you stylesheet the border away (which is a pain), they're still not
- * the same size
- * And so we ended up having this class only exist to contain all of the logic
- * for the nav buttons (which cuts down the code in MainWindow).
