Give an option to turn the New Conversation button OFF.
Not really much to say. Just please give us an option. It's not beneficial for everyone. If you can't see the square to type in, then use it. If you want the button then use it.
It's not the greatest option for everyone.

This is bugging me, I don't want to click an extra button just to start typing, it doesn't make sense to my feeble mind, please give us the option to just type away.
