yeah thats true, i open messages and then always forget to reply

I usually reply straight away, but I can see where it would be useful.

....you can easily sort by unread messages. So just read the messages when you have time for a reply.....and if you dont reply, just delete the message.

I usually reply right away too, but what I find annoying is only being able to see the few messages that I have sent out. I have quite a few that have not been read and it would be nice to know which ones hasn't been read.
