Hi Sylwia,
Thanks for the nice words, glad you love the plugin.
As for the export/import feature, this is a feature that we want to implement into CJT Pro and CJT Dev in the near future. We have been getting a lot of requests for a feature like this so this has been escalated to the top of the tasks pipeline. That said, I am sorry but I cannot provide an estimation for when it will be available.
Kind Regards,
Damian
