One thing that I've long wished for, and is becoming more and more important to us as we get list owners who never touch CMS is the ability for people to set individual list keywords via some sort of command interface. Right now, we end up having to make any list parameter changes ourselves for users who aren't CMS users. I'm sure there must be an email way of doing this, but at the moment, I'm not sure how, and I know that even some of my CMS users who own lists find the process so difficult that they ask us to make the (admittedly infrequent) changes necessary.
