Messages in languages other than English
In Messages you can customize the message. In my case make it Dutch. So the welcoming message is Dutch and when I'm offline it explains it in Dutch. But when you send a message while being offline the system asks in the next step for an e-mail adress. This message is standard and in English. This doesn't match our website and 'scares' away the visitors.
It would be a solution when you can customize this in your own language. Whether this is Dutch, Spanish or in English. If you can choose your own words it will be better converting these unknown visitors in known visitors.
