Yeah, I actually liked this when I first saw it, this feature isn't a pain in the ass, it's right to the point and easy to use. And to set up Plus for new users so they have it the way they want should be easy, and cut back on the people who have features enabled they don't and need to come here for help.
3.50 will be quite a landmark to increase the target audience of people who enjoy Plus! and this feature is just one of the small tweaks that will do this.
