I do like your idea of splitting the screen pager and the HTML aspect,
Ron. And yes, pydoc needs a cleanup.

I don't view code cleanup as something for this list. I view stuff
like "I want to hash out an idea on abstract base classes" and the
ilk. Code reorganization, etc. that are more software engineering and
completely new idea should still go to python-dev or python-3000.
Basically stuff where people might throw a fit over the idea should
probably come here until it is a solid idea. =)
So I agree with Thomas; this should go to python-dev.
