Resetting a settings screen

Every settings screen has Reset this screen to defaults next to Save Changes. It returns that screen's settings, and only that screen's, to their defaults; every other screen is left exactly as it is. You are asked to confirm first, and on the Search Console screen the confirmation warns that the client ID and secret go too. Reports and lists on the screen (redirects, the 404 log) are not settings and are not touched.

To be able to go back, export your settings first.
