I am happy to accept that, for some, overfull boxes are not errors; but
they are warnings, and I am asking only that certain categories of
warnings ( selected by the user at compile-time, and in addition to
errors,) should be able to trigger a non-zero status code.

"Draft mode" is a LaTeX concept; TeX, by default, shews the black lines,
but when one is working with 300, 400, 500pp+ documents, as I usually
am, searching visually for such things is not really an option.  If
TeXworks could be persuaded not to conceal the console log when such
warnings have been generated, a great deal of user time (and, probably,
the inadvertent release of faulty PDFs) could be saved.
