One room or several
You don’t choose a layout: the Board adapts to the number of rooms you add.
One thing at a time
No rooms, or one. Like most conferences and every wedding: the Board shows what’s on now, what’s next and the rest of the day, in order.
Several things at once
Add a second room and sessions sit side by side, like a festival’s stages. The Board shows what’s on in every room right now. A keynote can be held in two rooms at once.
