Subprojects and milestones have moved forward, but the UI is still unpolished and confusing.

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.

We have some concrete ideas for attacking project home pages and navigation (see some discussion in T10054) but haven't built it out yet. That's likely to happen next, then adjacent UI can form around that and then I can spend a week writing Javascript for workboards and typeaheads.
