Yo, so I kind of think that maybe Peach could use a toggle for her floating shenanigans. Maybe, like, if you hold down the air-dodge after the animation, she toggles into her floating stance? Or maybe taunt in the air and she toggles to it? I remember that Ness had a secondary "bat set" where you broke the taunt where he pulled out his bat, and then he had a second move set. Maybe Peach could have that? Folks using certain controllers like the GameCube controller could use something like that so they don't have to constantly hold Up on the stick and suffer from lack of horizontal mobility, especially when her aerial attacks are so essential.
