Hello missioneyes,
I have checked thread that Vinh replied you about this question, and then I tried to find this issue in our bug tracker system, but it is not exists.
I think that JB team did not decide develop it. I have just joined JB team for a few months since old developer has left, so I still do not have full information about this project.
I will create an issue on our bug tracker system and notify to JB team. We will try to release this plugin asap.
perhaps, we will start this plugin after version 1.0.2 for multilingual is released.
You can check status of this issue at
