Zach and I began by appraising our ideal GTD solution. We wanted novelty, but without monopolizing the user’s focus. At a time when desktop and mobile UIs were increasingly visually rich and illustrative, we took plenty of liberty in visual design. But, its core was a simple task list. It didn’t need to occupy the user’s screen and demand larger-scale management. It didn’t need to scale from simple list items to complex multidimensional and interdependent tasks.



Clicking a task opens a detail view showing further notes, start and end dates, attached files, and more info.
It needed a main view with tasks, groups of tasks, and mutually-exclusive groups of groups. Furthermore, we planned a detail view allowing for a task description, start and end dates, attached files, and further information.






I designed an app icon and interface icons for the Preferences window.

As a self-taught newcomer to product design and development, I often worked backwards from the product that I wished existed, designing what I desired others build. Like a lot of ideas then — it was fun, and left incomplete.
