I think we should put our efforts on getting a very sleek wallet out first. Emphasis on good looking, intuitive design. Get the core functionality in place with a great GUI, so as to distinguish Darkcoin immediately upon download. Value added features can then be added with further versions. I would also prioritize features associated with the actual sending of payments. Expanded functionality in this area would be much more apparent to the average user than some of the more complex features that others have suggested.
