Hello FLYqtFLY,
this plugin currently doesn’t include a language selector functionality for the front-end.
This feature might be added in future plugin releases but I can’t provide you a release date or guarantee about an actual implementation.
Note that we have a plugin for WordPress named Hreflang Flags that automatically generate flags based on the hreflang data available on the page. It’s a language selector that uses flags instead of the textual names of the countries. For questions associated with our plugins distributed on CodeCanyon please contact us through our website. Thank you.
