a specific entity view can become extremely cumbersome when it holds many properties (whether it's own, mirrored, calc) and relations. more over, different personas viewing an entity would probably have interest in different properties. we think it would be great if properties can be added to a "label" when designing in the Data Model which would explain to what "groupping" the property belongs to.
On the entity view, the labels can be either "tabbed" or folded in an accordion view.
