This is a real pain point for our customers and staff who work with specialised collections, the only way they get a realistic view of what is at an item location is to refine by availability first. Customers do not know they need to do this, so it is not very intuitive.

This one is pretty important to us. Without being able to choose if eContent is or isn't included in location filtered search results (we would choose for it to not be included) the location facet is basically useless.
