Very useful and convenient

Love the abiilty to open gmail right from the top menu without needing to open a web page. When you switch to another app, the mail window disappears, but immediately goes back to the same spot when you click it again. Very well developed app.

I would echo the request to be able to view mail from multiple accounts in one window. That was a feature i really liked from Apple Mail, and would like to see it here.
