The plugin currently uses wordpress i18n translations strings.
As a fairly new plugin, it hasn’t been translated into other languages, yet. Our big goal at the moment is to get it to a feature complete point. Translations soon to follow.
We want to make our plugin very compatible with third-party tools, Visual Composer, WPML, etc.
@malikh : Have you tried multi-lingual in the meantime ? WPML and Polylang should work, but I haven’t tried so far. And mightydigital is a bit evasive on that point. Thanks if you have something to report!
