Digging into a grouped result set currently displays the same pattern as digging into a particular attribute categorization from the top scope. This is suboptimal because a user who digs into an attribute from the top scope will benefit from seeing an enumeration of the types of attribute values in the dataset; it will not be so useful to a user who digs into a group from the top scope, because for instance, they may want to see the results in this group grouped by another attribute's value.
