**Creating a polished UI**

I need to focus on creating a polished user interface. It's essential to make sure it matches the expected tone. I'll inspect the package header to ensure compatibility. Maybe I'll check if there are any specific guidelines or standards to follow for this UI to make it user-friendly and visually appealing. It's all about enhancing the user experience, making sure everything flows smoothly and looks good at the same time.
