Not sure how prevalent very popular passwords are, so Id suggest if possible, it would be a real nice feature to see the worst offenders in order of most reused.

For instance "password", is its millions of instances actually #1 or is something else more prevalent?

Seeing the worst of the worst in terms of commonality/instances of use would be a nice tool for average users to gauge just exactly how bad that "Password1!" workaround really is.
