Not sure this qualifies as a bug, but I was just wondering why the message bubble for apps is always grey for both sent and received app messages. The iMessage convention is that the sent bubble is blue while the received bubble is always grey. This helps to differentiate received messages from sent message. Now, with message app bubble is always grey and fills more than half of the screen, which makes it a little less intuitive to figure out if the app-message was received or sent (esspecially if it's a collaborative app which exchanges app-states frquently).
It's just something I've noticed which mildly bothers me, has anyone else had a similar concern?
