Hiding read messages
If you don't wish to see items you've already read, such as in a very crowded group with many posts, you can hide read messages so they don't get listed.
To remove messages that you have already read from the message list, choose Hide Read Messages from the View menu.
Please note that hiding read messages only works in Messages view. If you wish to see new items in other views such as Files or Music, you should sort the view by date.
