How do we set the widget switcher ID?
Perhaps it would be convenient if we could set it directly on the button we want; On the button event drop down you would find a list of widget names that are contained in widget switchers from the widget blueprint?
Also a quick opinion; it would be great if we could edit the padding with the mouse, its much faster, more accurate and more user friendly, perhaps a keyboard button would activate the padding edition mode, then just click and drag the same way you would scale a widget.
