Could you make it so when we build our decks for tower, world bosses, and coliseum the girls are organized the same way as they are in collection girls window.
That's a good idea.
Someone above also suggested a one click button that automatically unequips all toys then equips the cards you chose for the next colosseum with the best toys.
These will be major quality of life improvement especially after the recent colosseum changes that made the mode unbearable.
However I doubt the dev cares.
