When translating a string, Pontoon displays all existing translations to other languages in the Locales tab. This is helpful for localizers that understand other languages than English and their native language.
However, the list can get pretty long sometimes, making it hard and time-consuming to find translations one can actually understand. To overcome this problem, localizers can now select preferred locales in the settings, which are shown on top of the list.
Translation counts from preferred and other locales are displated separately in the Locales tab header, making it clear if translations from your preferred list are available before even openning the tab.
