Universal Language Selector/New ULS/Preferred Languages

Please see this Phabricator ticket for more information: https://phabricator.wikimedia.org/T416512

Selecting preferred languages

To select a preferred language, open the language settings dialog.

If you have the ULS rewrite beta feature enabled, or if the wiki already has the new ULS active, you will see the Preferred languages tab in the settings dialog.

Click on that tab, and select your preferred languages.
