Kanban: Sort Per Column

In Kanban view, it would be very nice if each column could be sorted individually for instances where different statuses call for different sorting. For example, in a completed status column you'd likely want to see the most recently completed at the top (newest first). While for active projects/statuses, you might want to sort by varying sort methods, such as "oldest first," priority, manual sort (if/when it's added), etc. This could be implemented as either a replacement for the sorting in Kanban view as a whole or as a per column override.
