I've added a custom date field, Deadline, to Maniphest on my company's Phabricator, through the usual means. However, while it can be searched and sorted by in queries in the usual and expected fashion, it puts the tasks with sooner deadlines at the BOTTOM, instead of at the TOP. I can see cases where sorting would need to go either way, so Query needs a way to quickly toggle showing results in either ascending or descending order.
