First, let me say that I love this plugin. It makes managing scheduled posts and in-progress drafts about a thousand times easier. Thanks for your work on it.
Now the request: Have you considered publishing an iCalendar feed of this data as well? Even a read-only feed would be helpful, as we could see our scheduled posts on our regular calendars along with our other date-sensitive items.
This would not replace the calendar view provided now, of course, as we'll still need that to drag/reschedule and so on; this would just be another view into the schedule, one that can be combined with other calendar events.
