You have been asked to implement some program and you have been brainstorming. You got all kinds of ideas of how the user might be helped by adding this and that. You have taken into account all kinds of scenarios and provided lots of parameters.
Well, let me tell you that most probably you are over providing. Your imagination produced all these ideas, but they are not necessarily what the user needs.
Chances are that the user does not know what he really needs until you show him something. Save on your efforts. Produce a working prototype. Show it to the end user.
Take note of his observations and ideas, so that you can come up with things that are really useful for him.
