If I'm not mistaken, the lists on the translation and topic profile sections are sorted chronologicaly. This is fine by me, except for new topics.
If someone adds a message to a song translated a while ago (not appearing on the first page of the list), there is no way I am aware of to detect it but to browse the whole list of translations manually.
What I have in mind is a modification of the sort criteria so that songs/topics are sorted first on a "pending messages or not" criterion, and then chronologically as usual.
All the songs/topics with unread messages would then be displayed on top of the list, and get back in their usual place as soon as the song/topic page has been visited.
What do you think?
