Love the addition of swimlanes but makes no sense to have to navigate past a half dozen empty swimlanes. In our case we are grouping by a Custom field for Clients (since we still can't group by Folders?!?). Especially in Me mode there inevitably are many clients that are just empty so there is no need to clutter the view with these.

Attached is my recommendation of where to add an option for this in the View settings.
