Due all the respect to the devs - the new layout is not superior to the old one. It certainly look better and the back button on top-left is very welcome.

BUT: The input changements are not good at all. Send button disappears often and feels attached to the messaging-windows (you always have to scroll). While portrait mode is still usable, landscape mode isn't anymore at all.

I don't think we need such a large "Send" button, the other one was totally enough. And send button has to be within the input window - else it needs way too much space.

Smileys look really funny What icon set did you use? Was there a problem with the original Emoji's (copyright?)? But I think they should be a bit smaller. They tear apart the text too much. 3/4 of the actual size should be good.

I'm sorry for being critical, the app is absolutely amazing. I know the difficulties of UI design very well... But I think its easier to understand if I keep things clear instead of using too many nice words
