It would be wonderful if memories were sorted/shown by year, (if given) so that their life was in chronological picture/document order.
Go to anyone's detail page. Click on Go To New Person Page in the top right corner. Now go to their memories. On the right hand side you will see a button labeled Filters. Click there and you will find a choice to sort chronologically. This was released a couple of months ago as part of the new person pages.
