on mobile there is actually a selection mode (it’s the little square in the corner of the queue table that appears on touch devices), however this selection mode is terribly designed and i kinda just rushed it a long time ago. it has really bad touch targets especially for a mobile specific UI, and is not really intuitive or easy to understand at first glance
i think a redesigned selection mode should still contain that square in the corner, but instead of replacing the queue head on press, just show a popover that has different selection mode icons with good touch targets
