We improved the way that admins and editors can work with Locales. Their listing has been set to an alphabetical order, except for the default which always shows up first, in the following areas:

• In "Settings > Locales"
• In the Entry Editor's Sidebar
• In the Entry Editor's Locale's pop up. There it's also possible to select/deselect all the locales, helping users in spaces with many locales (more than 30, for example)
• In the Entry Editor's fields list
