Order stories by rank on work view (Stories swimlane mode), even if stories has no sub-tasks

we noted that, by configuring stories as swimlines, when a high priority story with top rank doesn't have sub-tasks, it's degraded down as "other issues", so the team can't see it at the top of the board to be the first to be started, as occurs on phisical boards.

it's really a unexpected behavior, because the issue ordering on plan and work views turns different, and it's forcing us to create sub-tasks even for very small stories.

it would be great to have an option (a checkbox?) to show stories w/o sub-tasks as swimline, like the others.
