Links from "X thinks Y's translation is very good".
If you follow the link from the translated text, it puts you into translation mode on the document, often at a different point. Once you select the relevant sentence you still cannot tell which translation was the one marked up.
Would it be possible to show the translation that Y made, so that you can evaluate it for yourself and hopefully learn something?
I think this may need to be separate from the normal marking of translations to avoid a "me too" effect.
