A bit confusing but, in official Messenger windows app there's feature that saves me a lot of frustration called as in title. Basically when you want to write a message to someone, you need to click on that edittext to be able to write. Well, in Messenger app you don't need to. You'll just click in the blank spot in conversation to have that window active and when you start typing, it will automatically put it into that edittext. This feature would be neat!
