You're right, the CB configuration can be fully translated, but not the other backend screens yet. All frontend can be translated but not the backend.
I don't have time currently to review all the backend code for translatability and add strings wherever needed, but if you want to do it, please PM me your email and url to this thread and i can email you latest version for doing it. You would probably need to have some free time in the next days to do it, but if you have the time, it would be a great donation to the project/contribution.
