WHAT YOU SHOULD KNOW

This is an MVP (Minimum Viable Product) release focused on core functionality. Advanced features like tap-to-send Morse, Koch method training courses, and additional practice modes are planned for future updates.

The quiz mode currently has visual/audio/vibration mode selection, though this feature is still being refined. The app works best with all output modes enabled for the most effective learning experience.
