The configuration should provide a flag for rendering small events to take up their actual size. The current default size of an event is the size of a slot, if the event's duration is smaller than the slot duration. It would be nice to be able to switch to a behavior where if an event is 5 min and the slot is 15 min, it will show up with the size of a third of the slot. This was possible in the Silverlight implementation, with the EnableSmallAppointmentsRendering flag set to false (for Silverlight that was the default behavior).
