Hi, Rub.
Thanks for your interest in our plugin suite.
We don’t have strong RTL support (some themes that integrate with our plugins, like Avada, might add RTL functionality to our plugin).
We have this information regarding translations:
If I’m understanding your buyers / user levels question, we do not currently have such functionality, but you might check for a similar existing idea at our UserVoice feature request site.
Last but not least, we have a pretty great Refund Policy so you can buy one or many of our add-ons and thoroughly test them.
I hope this info helps. Let me know if you have any follow-up questions.
