[Feature request] - Allow users to hold buttons as well as repeatedly tap them

[taeh98]

Please could you allow users to press and hold the plus/minus or up/down buttons an input element to continually increase or decrease the input's value whilst the button is held as well as allowing the buttons to be repeatedly tapped to increase or decrease the value (as is currently the case)? This would allow the user to use the buttons to select a new value that is much different to the current one much more quickly and easily than if they were only able to change the value by repeatedly tapping the buttons (as is currently the case). It would also be useful for the speed at which possible values are cycled through accelerates as a button is held.
