Manage All Subscriptions Data

When clicking "Manage All Subscriptions", you get a list of all your subscriptions which includes Subscription Name, Owner, Content Name, and Type.  The benefit here is quite limited as a result of the lack of information in the list.  We need columns that show the frequency and time of the subscription.  It would also be advantageous if you could make edits to those settings directly from the list view rather than having to go into each individual subscription.
