On a Mk1 and Mk2 a very handy feature is that double tapping a control can reset it to its default state. I use that all the time, as it saves time in for instance taking out any detuning.
On a MINI this is not possible as it has no touch screen. Yet, each encoder is also a press button. So having the option to set the press of a button as a means to reset to a default value could come in handy too
