Hi Anton and JP and thank you ever so much for your contribution!
You’ve given us a lot of food for thought and we truly appreciate your time and interest in this widget.
I’d also like to mention that we have Website Translator widget as our Coming Soon one, you can check how it’s going to look here - Website Translator - embed a multilanguage widget to your website! (2022). Perhaps that widget could also be of use in this feature realization.
And you’re welcome to vote for that widget request in order to get notified once it’s released here - Translation widget for webpage.
JP, many thanks for your thorough ideas and suggestions - all of them will be definitely considered by our development team.
Thank you!
