I use a wiki. As I dump thoughts onto it I generate documentation, "ToDo" lists, possible new features, critiques of existing features, problems I have to solve, solutions to problems I have solved, and links to other ideas and projects. Then I have a script that pulls the "To Do" and "Problems" sections into a prioritized work-list, and I'm off and running.
