In the next update or so, could you please add scroll wheel functionality? I can easily, and successfully, configure all of the buttons on my Pro controller, but without being able to configure the L and R buttons to scroll-wheel up and down, there are a multitude of applications that are just locked out of use. MineCraft and Terraria are just two examples, and for those who wish to use it for work, AutoDesk's AutoCAD program is another application you would need scroll-wheel functionality. Your program is the easiest to use, but this addition would make it by-far the only choice for Wii U Pro controller connections.
P.S. As an aesthetic addition, I suggest having what key each button is mapped to, in the Buttons key edit, displayed clearly, as currently (of 1.6) the keys mapped to the buttons are not displayed anywhere within the program to my knowledge, and to have it be displayed would immensely help.
Thank you for your consideration
