Subprojects and Milestones
Infrastructure for subprojects and milestones has moved forward, and some prototype UI exists, but it is mostly just a confusing, unclear mess for now. I didn't promote it since I think it will do more harm than good in its current state. We'll promote once it's in better shape, likely next week.
