Hello guys, there is a dot on title bar. I want to remove that dot and add menu bar to title bar. Here is screenshot: https://pasteboard.co/Hay6y3AM.png

You can configure the buttons that show up on the title bars under System Settings -> Application Style -> Window Decorations -> Buttons.
There is a button for Application Menu which you can drag up, which when clicked shows a drop-down with the application's menus.
