Drop Shadow feature/option for Foreground Selection. We heartily request you to add in this app. That is the "Shadow" feature for the Foreground object selected (Mask). Just like the shadow option in 'Assembly' app, where the shadow can be adjusted in its opacity, size & direction. It will be icing on the cake if you can also add the Transform option to the 'shadow' - so that the shadow can be skewed in XYZ axis.
