As we now have string variables, would be amazing to extend it to reflect the status of a certain copy. 

Here is why: 
It is always a challenge to integrate UX content designer workflow into agile process, most of the time the content is in review when the implementation has already started. 

I have recently started breaking down mockups to store approved copy in variables, however I do miss the ability to explicitly mark it as approved, so engineers would be able to see this status in dev mode. There is already ‘Text content’ section there, so small In progress/Approved hints would be really helpful.
