When I assign "Gestures" to the top button on my VerticalMX mouse, then the "Change Pointer Speed" action can't be assigned to any of the 5 gesture actions. If I want to have the "change speed" action accessible, then the only way seems to be choosing it instead of gestures. Wasting the whole button on that one action. But I want to be using gestures, and using the button for 5 different actions, but I want one of them to be "switch pointer speed". But that just isn't on the list when choosing actions for the gestures. Why?
