Make homepage full screen width
Though it might seem witty to have the message thread peeking out from the right side of the screen, in practice, I think it looks awful. People know that the next screen will appear when they tap a message. You don't need to clue them in to it.

Hallo, i got an german privat mailadress from "strato". Now i would like to use your app. Is there any chance to get mails from imap.strato.de and send mails to smtp.strato.de?
