Beautiful!
Since we keep data in the admin about chosen language, please consider passing it through the websocket json (would allow prompt translation and could be useful to plugins)

[zAlweNy26]

Nice idea, I will add that soon

[zAlweNy26]

Now on every message, the websocket sends this json:

{ 
    text: message,
    lang: localStorage.currentLocale,
    prompt_settings: settings 
}

This is great to involve the international community
