The mail listing including contact pictures limits the number of mails to view. Without contact pictures or icons, there can be more mails listed. An extra feature would be great to select the number of lines each mail should show. Only the message body or one or 2 lines of the actual message. I prefer only the subject. In such a way, much more mails will be shown in the main inbox mail list.
