hi grestord. I agree. There are a number of other improvements to S I'd like to make, aside from documentation. Since I wrote 's' I've learned alot, and I think I could make something much more accessible the second time around.
Unfortunately at the moment working fulltime on Spriter so I won't have time to work on any side projects like this for the time being. If you have any specific questions though, I or one of the other S users may be able to help you.
