It would be convenient if the Q&A user would be somehow informed whether the question is multi-language (i.e. requires multi-language input or not) when filling out the Q&A.
Currently, after changing the language of the document, the user has to go through all the questions and check for the missing input for that language. Therefore, it would be good if the need for multi-language input would be made more apparent to the user.
For example, the user could be informed about it in a very similar way it is informed when the question is mandatory (i.e. by additional color dot next to the question).
