feat: Visualize Parent - Children task relationship/hierarchy now that we have Boomerang

[neno-is-ooo]

Overview/Problem Statement

With the introduction of Boomerang Tasks, Roo Code now enables users to break down complex projects into smaller, manageable subtasks that operate in specialized modes. While this functionality significantly enhances workflow orchestration, users currently lack a visual representation of these task relationships.

The hierarchical connections between parent tasks and their children are critical information that users need to understand the structure of their workflows. Without visualization, users must mentally track which tasks are related, making it difficult to:

• Understand the current state of a complex project at a glance
• Identify dependencies between tasks
• Navigate efficiently between related tasks
• Communicate project structure to team members
• Plan future task creation based on existing hierarchies

As projects grow in complexity with multiple levels of nested subtasks, this problem becomes increasingly acute, potentially limiting the effectiveness of the Boomerang Tasks feature.

Proposed Solution

Implement a task hierarchy visualization system that provides a clear, interactive representation of parent-child relationships between tasks. The visualization should:

Key Capabilities:

1. Hierarchical Tree View: Display tasks in a collapsible tree structure showing parent-child relationships
2. Status Indicators: Visually represent the status of each task (active, paused, completed)
3. Mode Identification: Clearly indicate which mode each task is operating in
4. Contextual Navigation: Allow users to click on any task in the visualization to navigate directly to it
5. Summary Preview: Show brief summaries of completed subtasks on hover
6. Filter Options: Enable filtering by status, mode, or creation date
7. Export Functionality: Allow users to export the visualization for documentation or sharing

Integration Points:

The visualization should be accessible from:

• The main dashboard
• Within any active task view
• A dedicated "Project Overview" section

User Stories

1. As a project manager, I want to visualize my task hierarchy so that I can understand the overall structure of my project and identify any missing components.

2. As a developer working on a complex feature, I want to see which subtasks are completed, in progress, or pending so that I can track progress and prioritize my work effectively.

3. As a team lead, I want to share a visual representation of our project's task structure so that new team members can quickly understand how different components relate to each other.

Technical Considerations

• The visualization should scale effectively for projects with potentially dozens of related tasks
• Performance optimization will be needed to ensure the visualization loads quickly, especially for complex hierarchies
• The implementation should support real-time updates as task statuses change
• Accessibility considerations must be addressed to ensure the visualization is usable by all users
• The design should be responsive to accommodate different screen sizes and device types

Success Metrics

The success of this feature will be measured by:

1. Usage Rate: Percentage of users with Boomerang tasks who access the visualization feature
2. Navigation Efficiency: Reduction in time spent navigating between related tasks
3. User Satisfaction: Feedback scores specific to project organization and task management
4. Complexity Management: Increase in the average number of subtasks users create per project
5. Error Reduction: Decrease in task abandonment or incorrectly structured workflows

Priority

Priority: High - This feature is essential to maximize the value of the recently released Boomerang Tasks functionality.

This visualization feature is a critical companion to Boomerang Tasks and would significantly enhance users' ability to manage complex workflows efficiently.
