Absolutely needs a coherent ranking system like the stars in Adobe Bridge for photos, also colours to differentiate which tracks are developments of which. Lacking this feature costs us all time, I'm researching other generators that do have it.

pulling up these groupings with a simple click is ideal

To Add: Mark tracks on an easy to use ‘Todo List’ somehow

a snap to current playing song is needed

auto folder according to the above parameters could be an option.

and like the old ui where you could pull up ALL liked songs, songs should be "grouped" in folders by these "tags" described above. Again this is addressing the painful workflow issues of the new ui
