The preeminent mobile mail app is coming to desktops. Here's how the team got the feeling just right.
Do you remember the story of Mailbox? It was the iOS mail app that allowed you to control your inbox by swiping. Swipe left to archive, right to delete, etc. The approach was a huge hit.

And in what may be the greatest seal of approval, the iPhone's own Mail app adopted some of Mailbox's swipe gestures.
