I love the fact they have a Windows client now. However, I cannot seem to get back my side-by-side email view. I prefer to see my list of email headers vertically, and then when clicking one, I see the email to the right. Now they have some full screen nonsense as if my Windows computer is a mobile phone. If they're going to change the design and try to start charging, of which I fully support, at least don't change the design in a way that hinders they're existing user base.
