Oh yes right, this is very silly I know. It's only because changing the dimension values on touch screen is awful (need to focus on the input field then then tap the number). While on desktop, you can scroll on the input field to change it's value, which is more convenient.
Sadly, I made the "Pinch to change dimension" only on touch screen because it handle the pinch direction, so it can update x/y independently or together. While on desktop, the scroll would scale x/y together only.
However, glad you had fun with it :)
