Previous iOS versions of Mail did a fine job grouping conversations together, but during a hectic workday threads could get split up, making it hard to hunt down missing pieces. In iOS 8, Apple has made it easier to collect them all, wherever they may be. Tap on the More button after swiping left and you’ll find a new option to show related messages. Like magic, it will collect every relevant piece of communication for your reading pleasure. (MacLife)
