However, it should not be your regular analog piece of paper. What I do instead is printing out a nice template. A template crafted in LaTeX, which is the best typesetting system for technical stuff and technical people.
The goal of the project is to make a human-friendly, usable todo-list templates to be used. The templates can also be filled in by LaTeX itself, if you want and feel like installing a LaTeX compiler (XeLaTeX to be precise) — for all the other people, an empty template is available.
