Check if it's the last active user
Is it possible to add a check if the leaving user is the last one "editing" the empty pad?
I had a few instances where a user closed his tab while I was still discussing things and I had to refresh, because of the "This pad got deleted" message.
Reloading is not too much of a hassle, unless you have etherpad embedded in something else, which in my case is a videoconferencing system. :)
