Translators may accidentally leave some paragraphs without reviewing, which results in low quality machine translation to be published as part of the article. We want to find ways to draw the user attention towards those missing pieces at the right time.
Currently we show a message when the translation has a high level of unedited machine translation, and we show a reminder when the user tries to publish. In both of those cases we can highlight the paragraphs that need more attention.
