For a number of message types, our standard practice is to read and delete. This generally includes notification from appointment reminders and visit reminders. Unfortunately, these must be selected 1 by 1 and deleted to accomplish. Going away for a week results in a significant volume. The widgets in the messaging system support selecting multiple messages at once, but the action buttons don't act on those selections. Would be wonderful if I could delete multiple messages at once.
