The FooSettings apps have quite a lot of boilerplate just around creating a tabbed window with the same styling and the same row of buttons along the bottom. So, let's extract that out into a class we can reuse! :^) You create a SettingsWindow instead of a regular Window, passing a title and a flag to determine if a "Defaults" button is shown. Then call add_tab() to add tabs to it. Tabs are widgets extending SettingsWindow::Tab, which has methods for saving and resetting the values.
