The new app is great! Most important change of all is that my programmed actions went from consistent lag that could last as long as 10 seconds to now being immediate.

Please add one thing: On the old options app, if you set a shortcut to the horizontal scroll wheel, changing the scroll wheel speed would increase or decrease the repetition rate of the shortcut. As far as I can tell, the new app will not speed up or slow down the shortcut no matter how you adjust horizontal scroll speed.
