I have somehow switched the Cocos launcher app and Cocos Studio 2 into Chinese. I’m embarrassed to say I can’t figured out how to switch it back. 
Obviously the answer is “learn to read Chinese” but I’m a little slow at learning languages, so can anyone tell me where the preferences menu is?
Or, on a mac, where the prefs file is stored? I looked in the Library/Preferences folder at all the relevant plist files but none of them had a language setting.
EDIT: it’s the menu all the way to the right. it was just late at night, I was very tired and gave up before trying all the menus. Persistence is the key to game dev!
