You've got a shot at building a new Sparrow here. This looks really nice. Unsure that every email message needs a tab on the top, too—I think you could almost just rely on the left sidebar and treating the emails there as tabs. That, and some j/k shortcuts to quickly flip through the emails in your inbox would be great.

This is great feedback. Not sure about the top tabs as well as I spend most of my time inside an IDE, I got used to those. Maybe I'll add a hide option in settings?
