* **`OnEnable()`**: Loads the last used save folder path.
* **`OnDisable()`**: Stores the current save folder path for future use.
* **`OnGUI()`**: Displays the editor interface for selecting the terrain generator, specifying the file name, and choosing the save location. It includes buttons for selecting the folder and saving the settings.
