It doesn't seem that skinning is something that Adobe considered would need to be done in a skin class, for an item renderer. But, you can apply a skin class to them if desired. At each level: GroupBase, Group, DataRenderer, and finally ItemRenderer, you get additional functionality; and consequently, a little more overhead. For instance, if you used ItemRenderer instead of UIComponent, you could use the "hovered" state to control the visibility of the button. However, I think that you're going about it the most efficient way in creating AS item renderers instead of mxml; especially for ADG.
