When there is a discussion on a term/translation each time someone replies to it the icon lights up in Yellow, showing that we have unread messages.

This highlighting only goes away if the current user has the last reply on the conversation, meaning that a conversation that is 'resolved' can only be un-highlighted by making a comment, which of course highlights the thread for all other users, eventually rendering the highlight feature useless in large teams and long term projects, as most terms will eventually end up highlighted with no action needed.

There should be a way for a user to set a term/translation conversation as 'read' without affecting other users of the project.
