In Girls Selection window when you are selecting girls for Deck, when you select one element - it would be be better to have girls arranged in order of rarity (common, rare, epic, legendary and Mythic), it would make picking girls easier for Colosseum event or otherwise. Secondly when playing the game on Android device, now picking the girls has become better (one click instead of drag) but to remove girls is still troublesome, so button to remove girls from Deck would be great.
Lastly, this game do need now one button to remove 'ALL equipped Toys from any girl'.
