custom shadows WindowFX

Recently I lured in the WindowFX folder, found some bitmaps and some files with a wbd extension, I don't know how to make them on your own.

I think WindowFX should work different, more like Y'z Shadow. Instead of using bitmaps, the user should decide what size the shadow has directly from the application without the need of bitmaps.

Another feature in Y'z Shadow I really like is the opportunity to apply a shadow to the taskbar, that looks really nice, especially if you - like I - have it placed in the top of the screen.

Yea, I was looking into those folders too. As a matter of fact I even tried making some adjustments to wfs file within notepad and also created a couple of new bitmaps. However, my changed shadow did not appear in the list (within the WindowFX configuration window, even after restarting it). So I gave up on it.

It would be nice if the shadow-size slider was anabled. Does anyone know why that slider is always disabled ?

I thought the shadows should work the same as in Illustrator, where we can define darkness, bluriness and offset values.
