Multi User Selection to disable and delete Accounts

Sometimes i get into the situation, that i have to disable or delete several User Accounts at the same time. It would be great to be able to have a checkbox in front of each account on the admin page and a button to either disable or delete all ticked accounts at once.

The only problem i can see here, is that on deleteing an account you are asked to retype the accounts mail in order to confirm you want to delete it. Maybe this could be exchanged to type a ranom set of words each time?
