If I understand well, (2) is fit for ConTeXt users, but not for
LaTeX users (such as myself). Hence, in my opinion it is better to
keep things as they are organised in TeXShop. What should be done is
that your new version of (1) replaces the old one for the "mptopdf"
option of TeXShop's preferences, since it produces PDF versions of
each pictures, contrary to the old one.

Did you send the new version of (1) to Richard Koch? This version, as
I said, would make much more sense for the "mptopdf" option of
TeXShop. I've already used this new version many times, and up to now
I have not noticed anything wrong.
Many thanks for your very useful scripts!
