There are no specific settings within Clipper which will change the theme to RTL, so it will require some customization on your part in order to actually do this. There is information in the
WordPress Codex which specifically relates to this though.
I'm not aware of any specific Clipper customers using the theme RTL, however we do have customers using some of our
other themes this way. Our themes are not encrypted, so the necessary changes can be made by you if you wish.
