Hi, John,
you can take a look at https://zahnundvital.ch/
now it is translated with transposh, which is very practical for this modular theme, but not so good for SEO purposes
by inspecting the seems to be a huge collection of “id” and “class” and it can take forever to copy them for every page/post.
I guess if could only could get to visualize the language labels of each page , it would be fine. I magine I could click on the elements and translate them.
