One of things Notebook users have been asking for almost from the beginning is numbered list, like this:

1. First
2. Second
3. Third
   1. Third, Part 1
   2. Third, Part 2

My latest development build supports this, using MediaWiki-like syntax:

  # First
  # Second
  # Third
  ## Third, Part 1
  ## Third, Part 2

It isn’t quite ready for prime time; there’s a bug in the HTML widget I use for rendering “nbm3” markup that’s preventing me from assigning the numbers properly, and working around it would require significant changes in how I render a page. The Tkhtml3 developer, Dan Kennedy, has fixed the problem; I just don’t have that version of the widget yet.

I might decide to revamp my rendering scheme anyway, as it would produce more typical HTML than my current scheme. But the bottom line is that the next release of Notebook will support numbered lists.
