I was playing a little with Etoys and pen use today and found that it's hard to change pen color of SketchMorphs in scripts because their color category in the Viewer is not in use. But many times I may want to change the pen color of a SketchMorph so I thought a Pen Color category could be nice.
An other observation is that Pen color change is a little hard to accomplish because the color category give you access to the Player color and you have to remember to change to Players Pen color. A general Pen Color category would make the use a little easier because you would have the indirection already made.
What do others think ?
