# Enhance User Experience with Advanced Features - Plan 1

## Objective
Implement advanced task management features and improve user experience for the weekly scheduler including recurring tasks, categories, reminders, and priority levels. This plan focuses on extending the current task data model and UI components to support these advanced features.

## Purpose
This plan implements the core advanced features that enhance usability and functionality while maintaining a clean, minimalist interface. These features allow users to better organize, prioritize, and track their tasks.

## Output
- Enhanced Task type with new properties (recurring, category, reminder, priority)
- Improved TaskCard component with new UI elements for advanced features
- Enhanced TaskForm component with inputs for advanced features
- Updated CalendarGrid component to handle improved task rendering
- Updated taskPersistence with handling for new properties

## Tasks

<task type="auto">
  <name>Extend Task type with advanced properties</name>
  <files>src/types/task.ts</files>
  <action>Add recurring, category, reminder, and priority properties to Task interface:
- `recurring?: 'daily' | 'weekly' | 'monthly'` - indicates if task repeats
- `priority?: 'low' | 'medium' | 'high'` - task priority level
- `reminder?: Date` - reminder time for the task
- `tags?: string[]` - array of tags/categories for task organization

Keep existing properties (id, title, date, description, completed) unchanged.</action>
  <verify>Run `npm run type-check` to verify TypeScript compilation succeeds with new properties</verify>
  <done>Task interface includes all new properties and maintains backward compatibility</done>
</task>

<task type="auto">
  <name>Enhance TaskCard component with advanced features</name>
  <files>src/components/TaskCard.tsx</files>
  <action>Modify TaskCard component to render:
- Priority indicator (color-coded badges or icons)
- Reminder badge if reminder is set
- Tags display with visual distinction
- Recurring icon if task is recurring
- Improved styling for better visual hierarchy

Ensure component is responsive and accessible.</action>
  <verify>npm test passes and TaskCard renders with new features visible in UI</verify>
  <done>TaskCard shows all new features with proper visual indicators and remains responsive</done>
</task>

<task type="auto">
  <name>Update TaskForm component for advanced features</name>
  <files>src/components/TaskForm.tsx</files>
  <action>Update TaskForm to include form inputs for:
- Priority selection (low, medium, high)
- Reminder date/time picker
- Recurring task selection (daily, weekly, monthly)
- Tag/category input field
- Improved form layout and validation

Maintain existing functionality for title, date, and description fields.</action>
  <verify>npm test passes and form renders all new fields with proper validation</verify>
  <done>TaskForm includes all new fields with proper form handling and validation</done>
</task>

<task type="auto">
  <name>Update CalendarGrid to support new task features</name>
  <files>src/components/CalendarGrid.tsx</files>
  <action>Modify CalendarGrid to:
- Properly render new task features in the weekly view (priorities, tags)
- Handle any special rendering for recurring tasks (e.g., indicators)
- Maintain responsive design for both desktop and tablet layouts
- Ensure drag-and-drop functionality works with enhanced tasks

Keep existing navigation and task creation functionality.</action>
  <verify>npm test passes and CalendarGrid renders tasks with new features correctly</verify>
  <done>CalendarGrid properly displays all new task features and maintains functionality</done>
</task>

<task type="auto">
  <name>Update taskPersistence for advanced features</name>
  <files>src/lib/taskPersistence.ts</files>
  <action>Modify taskPersistence to:
- Serialize and deserialize new task properties (recurring, priority, reminder, tags)
- Maintain backward compatibility with older task objects
- Ensure all data is properly persisted to localStorage

Test with existing tasks to confirm no data loss.</action>
  <verify>Run tests that verify data persistence with new properties</verify>
  <done>taskPersistence correctly saves and loads tasks with all new properties</done>
</task>

<verification>
- All new features are visually displayed in UI
- All form fields for new features are accessible and functional
- Data persists correctly for all new properties
- Backward compatibility with existing tasks is maintained
- Responsive design works on both desktop and tablet devices
</verification>

<success_criteria>
- User can apply all new task features (recurring, categories, reminders, priority) to tasks
- UI correctly displays all new features with clear visual indicators
- Form inputs for all new features work correctly
- All data persists correctly with backward compatibility
- Application remains responsive and accessible
</success_criteria>
