We added an icon in the message list area

To help you know at a glance if you are the sender or receiver of the top puzzle in a message block, we added a new icon.

The arrow pointing into the box lets you know that you are receiving the puzzle and the arrow pointing out of the box lets you know that you are sending the puzzle. If there are two puzzles in play (you are trading) then you still know that the other puzzle is going the opposite direction.

Hopefully this will be helpful when you are looking at a long list of transactions and you can quickly see if you are the sender or receiver of the top puzzle.
