I'm playing around with the scripts. This is quite a cool feature!

I have a few comments till now...
1. Currently opening and closing a script region (i.e. switching from
viewing the code, and seeing the result) is equivalent to executing
the code. It would be nice to be able to view without executing. Or is
there also a secret key-combination for this?

2. I know that is a bit too much to ask for, but it would be nice to
be able to nest scripts, so that R can produce xypic code, which is
then rendered.

3. Currently, when you are editing a script, C-a goes to the beginning
of the line, not the beginning of the script. So you have to move with
the arrow keys. Not horrible...

4. It would be nice to have a way to open all script regions. They are
really hard to find.

Thanks a lot!!!
Michael
