Re: GDP: NR 1.1 Pitches vastly improved, more comments sought

Hi, Graham -

I noticed an issue regarding the "See also" on the TODO list: 

- all the commands like @seealso use a @subsubheading, but they
  appear as the same size as the @unnumberedsubsubsec headings (as
  you would expect).  Fix somehow.

I had noticed that, and wondered if adding a blank line between the end
of @seealso and the next @unnemberedsubsubsec would help clarify the
change in subject.
