What could be improved in this application? 
`````
Create a JavaScript CLI application in a single .js file with the following functionality:

1. The default command takes a directory path as input. The application traverses the directory to extract the following information:
   - The name of the directory itself
   - All filenames within the directory (including extensions)
   - All subdirectory names within the directory

2. The extracted information is stored in a hierarchically structured JSON file residing in the same directory as the script. The JSON file should have an identifiable name. The structure of the JSON file is as follows:
   - The parent directory is represented as an object with properties:
     - `name`: The directory's name
     - `type`: Always set to "directory"
     - `path`: The path to the parent directory
     - `contents`: An array that can contain both files and subdirectories
   - Each subdirectory is represented as an object with properties:
     - `name`: The subdirectory's name
     - `type`: Always set to "directory"
     - `path`: The path to the subdirectory
     - `title`: The title of the subdirectory (determined by matching with a dataset)
     - `contents`: An array that can contain both files and subdirectories
   - Each file is represented as an object with properties:
     - `name`: The file's name without extension
     - `type`: Always set to "file"
     - `extension`: The extension of the file
     - `path`: The path to the file
     - `title`: The title of the file (determined by matching with a dataset)

3. The application accepts a dataset provided by the user. The dataset is a collection of data units, each formatted as:
   ```
   Name: <value>
   Title: <value>
   Description: <value>
   ```

4. The `name` property of files and subdirectories in the JSON file is matched with the `Name` keys in the dataset. When a match is found, the corresponding `Title` value from the dataset is assigned to the `title` property of the file or subdirectory in the JSON file.

5. Once the JSON file is complete, the application generates an HTML file based on the JSON file. The HTML file visually represents the structure of the JSON file. The HTML file should have the following features:
   - Use a minimal neon theme
   - Allow subdirectories to be folded and expanded, with simple animations when clicking, expanding, or folding a subdirectory
   - Display file names, directory names, and file extensions in vibrant neon colors
   - Include tree edges to connect directories and files, similar to this
```
Parent Folder
├── folder1
│   ├── file1.txt
│   └── file2.txt
├── folder2
│   ├── folder3
│   │   ├── file3.txt
│   │   └── file4.txt
│   └── file5.txt
└── file6.txt
```
   - Show the following structure:
     - The ℹ️ emoji precedes each file and directory name, e.g., "📁 ℹ️ Directory Name"
     - File extensions are enclosed in round brackets and precede the filenames, e.g., "📄 ℹ️ (.ext) Filename"
     - When clicking the ℹ️ emoji (with a simple animation), a small pop-up message appears above the emoji, revealing the path to the subdirectory or file
     - Include a copy icon in the pop-up message to allow copying the path

6. The application prints the path to the generated HTML file to the console.

7. The paths to the dataset and HTML output are provided via the `--edit` or `-e` flag. An interactive prompt is displayed, asking for the paths. The provided paths are saved to a `config.json` file residing in the same directory as the script. The current paths can be viewed using the `--config` flag.

8. Include a comprehensive help menu accessible via the `-h` or `--help` flag, detailing all available commands and their usage.

9. Implement robust error handling with clear user feedback.

10. Use ES modules for modular code organization.
