I heartily agree with you. In most cases, more options are better. Sometimes, however, you run into a program that does only one thing, and does it so well that you can't imagine that you would need anything else.
In the case of the BT client, I can imagine a few things I would add to it if I thought I'd use them. For example, a history function might be nice. And if I'm going to add that, what about a nice search feature for finding BT downloads all over the net. If I add much more than that, I'm going to end up with some kind of new social software like some of the file sharing applications and services. You know, communities, chat, etc.
Oh, but don't let me distract you from your mini-review.
