Settings had grown to 21 rows in one list. It opens on five groups (This device, Display, GNSS and radio, Network, System); Enter opens one, Back returns to the groups, and Back from the groups leaves Settings. SettingsMenu holds the groups and which one is open (host-tested: every setting is in exactly one group). The guide, the how-tos, the README, the scripts' messages and the firmware's own name the new paths, such as "Settings > System > Firmware".
