Could we get virtual pads as widgets in umg? Native or maybe recreated in slate.
Those pads have some great and useful behaviors, and they could benefit from styles and umg functionality.
For eg. limiting pad to only one axis, and blocking thumb movement to it, would create great throttle widget, or slider.
Half of circle could be used in 2d games for aiming, without any need for vector math that some artists are suffering from.
