Events and Bookings: Full width, permalinks, max attendance

(1) On the Events>Settings>Appearance Settings I changed the Archive template to calendar and the Single event template to full width. I’m using the Network theme.

As you can see, the single events are not full width. How can I make this work correctly?

(2) Also, is there a way to use a different permalink structure for events?

(3) Still REALLY need the functionality to cap attendance at an event. Is this forthcoming?
