SMS messages are not sorted per date. Moreover, both in the Archive folder and in the Outgoing folder, it is possible to see only the reception date, and not the sending date.
In the Outgoing folder, it would be nice to have a column containing date in which the SMS has been sent.
In the Archive folder, it would be nice to have only a generic date column, which indicates the reception date in the case of received messages (IN), and the sending date in the case of sent messages (OUT). In this way one can see the complete conversation in chronological order.
