Currently, the comments system is a mess. Translators sometimes need to discuss some problem which is bound to their language only, but due to the way the comments system is built now, everyone else in the world sees their conversation. This creates one big stream of unrelated messages in different lanaguages and alphabets. It's a really terrible user experience.
Or even more simple:
Tanslators see by default only the comments of their current language, but can enable to see the other language's comments too.
Maybe there should be a "global" and a "language-specific" comment section...
- Global: every user in every language can see the comments
- Language-specific: for example, if a hungarian user (translator, etc) writes a comment in the "hungarian comment section", only the hungarian users can see the comment
But translators / proofreaders of other languages often participate on discussions in foreign languages. This is a major advantage which outperforms the major disadvantage of being cluttered.
When discussions about single translations in a certain language tend to grow too large, simply open a discussion thread, post a comment in the translation comment "Please discuss here <link to the discussion thread>"
see discussions on other languages about a same word help me often, especially for lack of context... but you are right, some times (often) the discuss is about an issue that is specific to the target language.
