3. Advanced customization: Zsh offers extensive customization options, allowing users to configure various aspects of the shell to suit their preferences. This includes customizing prompts, key bindings, command-line editing behavior, and more.

4. Plugin support: Zsh has a vibrant community, and there are numerous plugins and themes available that enhance its functionality and appearance. These plugins can extend Zsh with additional features, such as syntax highlighting, git integration, auto-completion for specific programs, and more.
