The latest update changed the appearance of messages, making it less user friendly. I used to be able to open a message, then select "mark as unread" before closing the message. Very quick and easy. Now, though, the only options are delete, reply, reply all, forward and edit. I have to slide the bottom panel up to view more options, of which the mark unread option is still not show. I have to select the "more" option to open yet another panel and then look through 30 options to find "mark unread". how do I fix this?
