> "I can't do this, I can't do that", "I'd like this feature, why don't you have it?" and "This is incomplete" The key about that is to not worry much about it: things are not as bad as they seem, and they are not as good as they seem. If someone tells you "I'd like this feature, why don't you have it?", probably what you don't realize there is that this person is currently talking to you and is talking about your product. That's a lot. Starting from there you can go further like for example start to charm him/her.
