Sure, and I've also considered having two 'columns' of options, a paginated approach with a 'next/previous' button or a 'Mass Effect' style response ring, but it's also about keeping things simple. Too many options can leave a player feeling overloaded with possibilities. But we'll see how it goes.
Right now, any extra UI is also extra development time, and even a small menu can be time-consuming to construct. If there's a lot of demand for a more fine-grained approach then I may implement it, but right now I'm concentrating on new areas, girls and content :)
