In Board view, you can select multiple Sort options (e.g. Due Date & Priority). Right now, that list is static and it seems to order from top to bottom in that list of options. I'd like to manually order them so I can tell it which to sort by first, then second. Since Priority is listed above Due Date, it sorts Priority first, then within a given Priority, it sorts by Due Date. For my system, I'd like to put Due Date as the first order sort, followed by Priority - which isn't possible today.
