Icon on button functionality needs to be extended.
Image alignment (Gravity): Top-Left, Top-Center, Top-Right, Center-Left, Center-Center, Center-Right, Buttom-Left, Buttom-Center, Button-Right.
As you already have Top-Left and Center-Center, you just need the other 7 options.
And it would be nice if property is called Image alignment - this would put it in line with other develop environments.
If you don't use FILL on icon, button should retain the selected background color (thus button background color should be selectable in any case).
