# Gang Board Sorting - Implementation Notes

## Goal
Sort tasks by last updated date (descending) so the most recently updated tasks appear at the top of each section.

## Files Modified

### 1. `src/components/BacklogView.tsx`
Added sorting to three areas:
- Current sprint tasks
- Backlog tasks  
- Other sprint sections

```typescript
// Sort tasks by updatedAt (descending) - latest first
const sortByUpdated = (a: Task, b: Task) => 
  new Date(b.updatedAt).getTime() - new Date(a.updatedAt).getTime()
```

### 2. `src/components/SprintBoard.tsx`
Added sorting to sprint board columns:
```typescript
const sprintTasks = tasks
  .filter((t) => t.sprintId === selectedSprintId)
  .sort((a, b) => new Date(b.updatedAt).getTime() - new Date(a.updatedAt).getTime())
```

## Where It Applies

1. **Backlog View** - All task lists sorted by last updated
2. **Sprint Board** - Tasks in each column sorted by last updated
3. **Current Sprint Section** - Tasks sorted by last updated
4. **Other Sprints Sections** - Tasks sorted by last updated

## Testing Checklist

- [ ] Open backlog view - most recently updated task appears at top
- [ ] Open sprint board - tasks sorted by last updated in each column
- [ ] Edit a task - it moves to top after save
- [ ] Create new task - appears at top of its section

## Deployment Status

## Notes

- Sorting is client-side (happens in component render)
- No database schema changes required
- Works with existing drag-and-drop functionality
