Build a standout React web app for creating Software Requirements Documents (SRDs), here are some features and enhancements to ensure it's comprehensive and user-friendly for developers:

1. Clean, Intuitive UI
Drag-and-Drop Editor: Allow users to easily create and rearrange sections of the SRD using drag-and-drop.
Predefined Templates: Offer templates for different types of software projects (e.g., web apps, mobile apps, APIs), making it easy for developers to select a starting point.
Customizable Sections: Users should be able to add, remove, and rename sections to adapt to specific project needs (e.g., adding specific regulatory or compliance sections).
Markdown Support: Support for markdown to let developers use lightweight text formatting, making documentation more efficient.
2. Dynamic Functionalities
Real-time Collaboration: Allow multiple developers or stakeholders to edit the SRD in real-time, similar to Google Docs, with live updates and change tracking.
Version Control: Integrate Git or other versioning systems so that every change made to the SRD is tracked and can be reverted if necessary.
Commenting System: Allow inline comments in every section of the SRD for team members to discuss and clarify requirements.
3. Enhanced Developer Tools
Auto-Suggest for Requirements: Based on common project types or the specific needs of the user, suggest requirements for functional, non-functional, and technical aspects.
Code Snippet Integration: Enable developers to include example code snippets or API details directly in the document, with support for syntax highlighting.
API Integration: Provide integration with tools like Swagger or Postman for developers to import and document APIs within the SRD easily.
4. Advanced Features for Usability
Requirement Prioritization: Allow users to prioritize requirements (high, medium, low) and visually track the status (not started, in progress, completed).
Requirement Dependency Mapping: Show relationships and dependencies between different requirements, helping developers and project managers understand how requirements affect one another.
Document Export Options: Allow users to export SRDs into popular formats such as PDF, DOCX, or even LaTeX for developers who need formal documentation.
5. Security and Privacy
User Authentication & Role-Based Access: Implement secure authentication with role-based permissions. Some users might only be allowed to view the document, while others can edit it.
Data Encryption: Ensure that sensitive project information is securely stored and transmitted with encryption.
Backup and Recovery: Provide automated backup of documents, with easy recovery options in case of data loss.
6. Project Management Features
Integration with Task Management Tools: Allow integration with project management tools like Jira, Trello, or Asana so developers can link requirements to specific tasks and track progress.
Milestones and Deadlines: Enable users to set milestones and deadlines for different requirements, with notifications for upcoming due dates.
7. AI-Powered Features
Natural Language Processing: Help developers write clearer requirements by providing suggestions to improve clarity and detect ambiguous or incomplete requirements.
AI Assistant for SRD Creation: An AI-powered assistant that helps generate initial drafts of the SRD based on user inputs or project descriptions, saving time.
Requirement Validation: Use AI to validate if certain requirements are feasible, given the project's scope and constraints, flagging potential issues early on.
8. Mobile and Offline Support
Mobile-Optimized Version: Ensure the web app is fully responsive and accessible on mobile devices, allowing developers to review or update documents on the go.
Offline Mode: Enable offline functionality, so developers can work on their SRDs without an internet connection, syncing changes when back online.
9. Analytics and Reporting
Requirement Coverage Reports: Provide visual reports showing which areas of the SRD have more or fewer requirements and highlight gaps or overlaps.
Progress Dashboards: Include a dashboard to track overall project progress, requirement fulfillment, and risk areas in real time.
10. Glossary and Use Case Generation
Auto-Generated Glossary: As users write technical terms and acronyms, the app should automatically add these to the glossary section, with definitions pulled from a preset or user-defined dictionary.
Use Case Templates: Provide ready-to-use templates for common use cases. Allow users to add custom actors, actions, and flows using an intuitive interface.
