Summary of Changes

Hello @FredCoast, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the string analysis tool by introducing robust tagging functionalities to the web application and integrating these capabilities with the Python backend. The changes empower users to customize and manage their string data more effectively, improving both the interactive experience and the utility of the generated analysis results.

Highlights

  • Enhanced Web Application Tagging: Users can now add custom tags to individual strings directly within the web interface and apply tags to multiple selected strings via a new mass-tagging feature.
  • JSON Export Capability: A new button allows users to export the current string data, including any newly added tags, as a JSON file.
  • Improved Web App Responsiveness: Significant CSS updates have been implemented to address scaling issues and improve the user interface's responsiveness across different screen sizes and DPI settings.
  • Python Backend Integration for User Tags: A new command-line argument (--expand) has been added to the Python tool, enabling users to import their custom-tagged string data from the web application into a personal expert database.

Code Review

This pull request introduces significant new functionality, allowing users to add custom tags to strings both in the web UI and via the command line, and then persist them to a user-specific database. The changes are extensive, touching both the Python backend and the React frontend.

In the Python code, the new --expand argument and related functions for updating the user database are well-implemented, but there are some areas for improvement regarding code duplication, function naming, and argument parsing complexity. I've left specific comments on these points.

The web app updates are great, adding individual and mass tagging, JSON export, and improved responsive layout. The implementation is solid, though I've noted a few areas where performance could be improved and some leftover debugging code that should be removed.

Overall, this is a valuable addition to the tool. Addressing the feedback will improve the code's maintainability, robustness, and performance.

Using JSON.parse(JSON.stringify(data)) for deep cloning the state object is inefficient, especially for large datasets, and not idiomatic in React. Each time a tag is added, the entire data structure is serialized and deserialized. This can lead to performance issues. Consider using an immutability helper or manual recursive cloning to update the state more efficiently by only creating new objects for the parts of the state tree that have changed. This same issue exists in handleMassTagSubmit.
