I must say I really enjoy it. I like that it looks like a chat, and I like that the persons number and photo are displayed at the top, it stops me from saying the wrong things to the wrong people. As for the three lines of typing, a quick scroll up and you can see what you have written already.
Personal opinion is I really like it, since I got 5.0 a couple days ago. For those who haven't had it before, they may not, but it was a feature that users were demanding.
I come in last, but just in time for breakfast.
Keep it through, Keep it through, forever blue.
