I think it takes up too much screen real estate, and doesn't add anything to the view.
Idk about Mint in particular. There's a way to do this in most de/wm. I would start in the system settings where you can choose light/dark themes. Then just go top to bottom in the system settings.
Sorry I couldn't help more
Edit: If you don't go through settings systematically like this often, it's good practice. You always find things you'll use later.
