## What's In Progress 🔄

| Task | Status | Notes |
|------|--------|-------|
| Tree Editor | Functional | Core editing complete, polish ongoing |
| Tree Editor Validation | Partial | Basic validation working |
| User Preferences | **Partial** | Dark/light mode complete, export format default pending |
| TypeScript strict mode | Warnings exist | tsconfig needs `strict: true` |
| Starter decision trees | **7 of 7 complete** | Comprehensive seed script created |
| Markdown Rendering | **Complete** | Session player + node editor |
| Deployment | Not started | Railway/Render planned |

---

## What's Next (Priority Order)

### Immediate (This Week)
1. Complete Tree Editor validation (required fields, orphan detection)
2. ~~Add User Preferences (theme toggle, export format default)~~ Theme toggle **COMPLETE**, export format pending
3. Fix TypeScript strict mode warnings
4. ~~Create remaining 4 starter decision trees~~ **COMPLETE** - 7 trees seeded

### Soon (Phase 2 Completion)
- Team management
- Mobile responsive improvements
- Tree versioning UI

### Later (Phase 2.5)
- Personal tree branching
- Step library with ratings
- Tree forking and sharing
