It would be helpful if in the messages window, we could have the option to show us our most recent chats, separate from those we pin.
Currently, after pinning many chats (that go to the top), we have to scroll all the way down to see a recent chat.

The "unread" filter isn't sufficient because ongoing or recent chats you've received just a few minutes prior will appear way below in the list of chats.

Thanks for your consideration.
