Well, I was using the Unlist function as a delete function for the people running it. That way I can recover what they "delete" by reimporting it if necessary. Having it rename the folder to unlisted_xxxx where xxxx was the previous name would just make it easier to find galleries that have been "deleted" via unlist. I could then decide what's old enough to delete and which I should keep around in case the need for recovery arrises... I don't want to make clients rename stuff before they delete it. Doesn't make much sense to the client.

But I suppose that'd be too good to be true ;) Thanks anyhow!
