So, Private Messages all show up into a single mix. I already made a post about being able to sort them by character, now, it would be quite nice if there was another thing. Sometimes, you don't want to let a name disappear by closing entirely, but you would like to be able to 'archive' a conversation. It would not show into the Inbox like others, but rather into an Archive page. That way, you are able to keep recent conversations and older ones separate!
