Mail: status bar and display of pending mails/downloaded mails

Hi there,

it would be great to know, that all mail account preferences work perfectly by showing up a status bar with the exact number of pending mails on the mail account server. Would be much more trustworthy, than a nearby single rotating wheel after clicking the “refresh” button on the top right, without knowing exactly what happens next (did I receive anything? Did I miss anything? Was there just spam? etc).
