list all subscribed users

It would be nice to list subscribed users and the comments they are subscribed to. This helps give an indication of the value of the module and it allows an admin to unsubscribe them more easily. I see this as two new tabs which would list:

"Subscribed users"

Header: E-mail | Operations
user1@example.com | view subscriptions [linked to a listing page] | unsubscribe [linked to unsub]
user2@example.com | view subscriptions [linked to a listing page] | unsubscribe [linked to unsub]
...d

"Subscriptions for user1@example.com"
user1@example.com is subscribed to

Header: Title | Operations
node-title1 | unsubscribe [linked to unsub]
node-title2 | unsubscribe [linked to unsub]
node-title3 | unsubscribe [linked to unsub]
...
