This isn't a bug per se, but I don't care for how an item in mini and a pinned item look aesthetically so similar except for their copy buttons, which look very different. I realize that the button in the pinned item exposes more functionality, but I think a more aesthetically harmonious solution is possible.
The new copy buttons don't feel like an improvement, they don't feel like a native macOS control, the styling of the dropdown menu no longer matches the styling of the primary button, and it seems like a very visible design incongruity between the main app and pinned items on the one hand, and mini on the other.
