## Priority Gap Resolution

### High Priority (MVP Blockers)

1. **Email system** - Verification and password reset cannot work without email
2. **Rate limiting** - Security risk without it on public redirect
3. **QR scan tracking** - QR exports need `?qr=<id>` param for scan attribution
4. ~~**Geo breakdown** - GeoIP integration for country-level analytics~~ ✅ Complete
5. **Projects UI** - Backend exists, needs frontend

### Medium Priority (MVP Polish)

6. **Account settings page** - Users need to update profile
7. **Domains UI** - Backend exists, needs frontend
8. **Usage quotas** - Enforce plan limits
9. ~~**QR shape presets** - More customization options~~ ✅ Complete (Square, Rounded, Dots)
10. **Custom date range** - Analytics flexibility

### Lower Priority (Post-MVP)

11. UTM builder
12. Soft delete for links
13. Print-ready QR options
14. SSO integration
15. Stripe payments

## Notes

- Backend uses FastEndpoints (not traditional MVC controllers)
- Vertical slice architecture: features in `src/api/Features/{Feature}/`
- All endpoints require JWT auth except public redirect
- Default domain: use app's domain until custom domains implemented
