I've looked and can't find an answer yet. When I go into Messages folder I just want to sort it so all unread messages, missed calls, etc. all appear at the top of the list. I don't want this as permanent setting, just want to be able to do this when cleaning up Messages folder. It's a quicker way to mark them read, delete, whatever, rather than scroll down through the list.
Thanks, that works for me. Doesn't sort them all at the top as I was hoping to achieve, but at least it hits each unopened message down the list, so saves all that scrolling.
