I think Gary was asking if we can add to the wish list in this thread.

Well, if you can, then here's mine.
If not, then please feel free to delete this post.

I'm not sure anyone's mentioned this, but doing shadows is something that is problematic, in my opinion.
If you want to draw a shadow that is sharp near the object and then gets softer further away, this is difficult to do.
The way I do it, is by combining two or three images and using transparency etc... Very cumbersome and sometimes a bit hit and miss.

My thought was that if you could have graduated feathering, then this could be used on the shape that you've drawn for the shadow.

Does this make sense?
