I can't hep but think, that my brain is trying to tell me something, when I find myself fumbling with mail.google.com.
In the gmail app on Andera, viewing a message displays the message list off to the side as a fragment. None of that < or > buttons for Android. I'm so used to it now, that in Chrome, I was almost thinking, "WTF where did my message list go?" when I saw the usual "Labels" side bar. Oi vey, I need to stop using PC's so much!!!!
