Also, once the API is unlocked, YAML based loading can be added to the Bukkit manager, or even Property files still. This means you'll be able to let your users manage the language strings too. Figuring out that kind of stuff is why I haven't opened up the API yet. right now I only have the Locales class, but I'm pretty sure I need to expand this to BukkitLocales, SpongeLocales and BungeeLocales too. EDIT: 1/6/2018 - The work discussed here has been implemented!
