hi, thanks for your reply.
you can test it by yourself by creating a button with a hugh different between the regular state and the haver state.
If you have a button with maybe an arrow to the right and its have to slide to the right by hovering, its cool to be slowly so you can follow the animation. But when the button changing its color, its more effektiv when the color change is instantly.
So a speed configuration for the buttons like you have for the hover interactions will be great.
