I feel that features such as the Shadow Tool get added, and then that's that. The Bitmap Tracer is another example. I do not see a lot of effort in revisiting existing features and making improvements. I have said this before, I would be more interested in a version, perhaps a .5 version that offers no new features, just fixes bugs that have existed from many versions past and/or that improves standard features such as the Shadow Tool and Bitmap Tracer.

For years we have been begging for grayscale support and spot color support in PDF files. This would be a lot more valuable to me than some wizzy new feature that I may never use.

As far as selecting just the shadow, Ctrl click on shadow and the start bar will indicate the shadow is selected.

And I just created an object, added a shadow, changed the shadow color, blur, and transparency, then copied and pasted attributes to several other objects. Same thing with the Glow shadow.
