Refined prompt:

Design and implement a robust, user-friendly Kanban project management system using HTML5, CSS3, and JavaScript. Your goal is to create a highly flexible and customizable Kanban board that allows teams to efficiently manage tasks and projects.

Key requirements:

  1. Board Layout and Structure

    • Create a default board layout with columns like To Do, In Progress, Done, etc. Ensure the layout is clean, intuitive, and visually appealing.
    • Implement a dynamic column structure that allows users to add, remove, or reorder columns effortlessly.
    • Support custom column names and descriptions.

  2. Card Functionality

    • Develop a card system that allows users to create new cards with rich text formatting (bold, italic, underline, color, etc.).
    • Include card attributes such as labels, due dates, priority levels (high, medium, low), and subtasks.
    • Implement card assignment with user avatars and filtering by assignee.

  3. Drag-and-Drop Interaction

    • Integrate a smooth and intuitive drag-and-drop system for moving cards between columns.
    • Add real-time animations to indicate card movement and position changes.
    • Ensure the interface remains responsive and functional when multiple users are interacting with the same board simultaneously.

  4. Card Comments and History

    • Develop a commenting system that allows users to add comments to each card.
    • Create a timestamped activity history for each card, tracking changes in priority, due dates, assignments, and comments.
    • Display the activity history in a clear and organized manner.

  5. Board Customization

    • Implement a color theme system that allows users to change the overall visual style of the board.
    • Provide options to adjust font sizes, card colors, and column border styles.
    • Ensure all customizations are saved and applied consistently across different board views.

  6. Multi-Board Functionality

    • Allow users to create multiple boards and switch between them quickly using a sidebar or dropdown menu.
    • Implement board-specific settings, such as default column order and color themes.
    • Enable users to pin frequently used boards for faster access.

  7. Data Persistence

    • Utilize localStorage to save board data, including card information, column order, and custom settings.
    • Develop an export/import system that allows users to share board data in a JSON format.
    • Ensure data is restored correctly when the user revisits the board.

  8. Responsive Design

    • Design the interface to adapt seamlessly to various screen sizes and devices.
    • Optimize the layout for mobile devices, ensuring all features remain accessible.
    • Maintain a consistent visual style across different screen sizes.

  9. Keyboard Shortcuts

    • Implement a set of keyboard shortcuts for common actions like creating a new card, moving a card, or filtering by assignee.
    • Document the shortcuts clearly and make them easily discoverable within the interface.

Your solution should balance flexibility, ease of use, and performance. Aim for a polished, professional look that can be used by teams of various sizes and complexities.
