AFTER:  Settings in primary navigation bar (1 click to access)

✅ Code Organized

BEFORE: Complex dual-state navigation, scattered render functions
AFTER:  Single activeView state, 5 focused view components

✅ Type System Simplified

BEFORE: MainTab, LegacyTab, WorkflowTabConfig, StepMeta types
AFTER:  MainView type, NavItem interface, NAV_ITEMS config

🎓 Key Learnings

Architecture Improvements

✅ Single Source of Truth - One NAV_ITEMS array, not three separate ones ✅ Type Safety - 2 focused types instead of 4 scattered ones ✅ Clean Separation - Each view is independent, easier to test ✅ Maintainability - Clear structure makes future changes easier

Code Quality

✅ Zero TypeScript Errors - In the refactored component ✅ DRY Principle - No data duplication ✅ Clear Naming - activeView is clearer than activeTab + legacyTab ✅ Proper Hooks - Correct React usage with useCallback

User Experience

✅ Improved Navigation - 5 focused views vs 7 scattered tabs ✅ Better Access - Settings in primary nav, not buried ✅ Professional Look - Sticky navigation, consistent styling ✅ Mobile Friendly - Responsive design works well on all screens
