Current Status and Important Notice

This is a modernized port currently in active development. Users should expect bugs and issues as we continue stabilizing the application. This version is intended for testing and experimentation, not production use. Bug reports and contributions are welcome as we work toward a stable release.

Immediate priorities include:

• Continued bug fixes and stability improvements
• Performance optimizations for extremely large datasets

Deferred for future releases:

• Bootstrap and jQuery migrations (kept current versions for stability)
