The Tracks and Groups lists met the Edit and Mix windows at a faint one-point line. A 10-point grey gutter with dark edges now runs down the panel's right side and carries each list's scroll thumb when the list is longer than its space: drag it, or click above or below it to page. egui's own scroll bars are off there.
