It does - ever since the "new new UI" I had been using that exclusively. Still, there's a limit in how many pages back you can go in your comment history to edit / delete. If you happen to find one of your old comments by other means, you can still edit it - but not through your own history. But I see that long before that caps out, some of my comments have already been restored, after having been gone for months... Those fuckers...

I was - I had waited a bit too long and the API was locked down, I was under the impression that the deletion tools no longer worked (and a bit hesitant to give my login / password to some third party tool)
