Total value of Salesforce opportunities or # of cases as a column in the Idea list

When prioritizing ideas, they are easily filtered by vote count. What would also be useful is total opp value and case count. 

As you can only see the aggregated value of opps when clicked into an Idea, it would be great if the total amount could be visible as a column which can be filtered, sorted and exported. Representing the number of cases attached would also be beneficial.
