Can you add the following?
breadcrumbs - eventcalbread: This will allow us to skin these breadcrumbs differently than the site breadcrumbs as it is not contained inside of the eventcalendar panelwrapper . This would need to be added to each view available in Event Calendar Pro.
Add classes to the individual views to differentiate them from each other.
If at all possible, wrapping as much of the content in each view in an element with a specific class would really help with skinning.
