It wasn't apparent to me until the PC release why trying to switch techniques and photon arts in Customization felt off. That screen was designed to drag and drop them with a mouse, even swapping them without leaving the pallet.

If you select one using a controller, it makes a sound but has absolutely no function. Would it be possible upon selecting, that the art/technique floats above the cursor allowing you to place it in a pallet slot? I wouldn't even mind if I had to hold the button, then release. I don't think there is a reason why this should stay exclusively a mouse function. I feel this would make the Customization screen less cumbersome and more intuitive for console/controller users.
