level slider

its something really wanted since many years now. +1 or +Max just don't make sense and its not practical at all. If they add Arrow to allow us to choose the level we want will be very appreciated. By example I want to improve to 7. I am forced now to do +1 like 7 times and the animation is slow.

With Arrow we can choose the level we want by example ^ 8 V or why not if you want 14 level ^ 14 V

Arrow will make our life more easily into the game. Remove the +1 and Max option
