I like your thinking. In my case, I'm going to try to put all the inputs
on a floating palette rather than integrated into the cells. I may not
be able to do that, however, so your comments have proven valuable to me already.

Another question: Does anyone know how Illustrator, Quark and the like
handle the scrolling around a big document? That information would shed
some light as well.

Also, I remembered Inside Macintosh, and am reading about Gworlds right
now (Duh!)
