Hello,
I think it would be a cool feature if the mix window has the option to hide/show an arranger track or marker track.
This way you can jump to certain segments of the song while mixing with a fullscreen mix window (or all screens with several mix windows).
I know you can already do this using a marker track and hotkeys but perhaps having an arranger track as a small bar above the routing section or below the track labels in the mix window can ease workflow without using key commands.
