I'm not job seeking at the moment but when I was, I would have paid for a site like this that would allow me to create tailored resumes for each application, manage the list, and ideally have some version control. Might be outside the scope of what you were working on but definitely a way to go from side project to side business. Contact me if you'd like more feedback.
I'd be interested to hear how people with profitable side projects went from side project to profitability.
