@jarrod And the sidebar/window control madness:

Image of a text discussing window controls in applications. It explains that the sidebar appears in a floating state, reflecting ambient colors, making it look translucent. The sidebar reflects surrounding colors even with “Reduce Transparency” enabled. Window controls within the sidebar appear to affect the sidebar rather than the application window. This design allows content to be displayed underneath the floating sidebar. The text highlights how this is seen in the Music app and questions the purpose of placing content under the sidebar.
