Hello, we have a similar issue. Our content is available in 4 different languages: English, Thai, Russian and Chinese.

We are using relations to create content categories and subcategories and we have commissioned the category’s translations to an external translation service.

The problem comes when we create new content and we need to assign a category or subcategory, because nobody is able to read Chinese (for example).

It would be great to keep relations synched in different laguages or at least the “default” language in brackets near the relations.
