If I understand you right, you should change the 'title_single_before' to 'title_before' in _html_header.inc.php on line 33

Very nice! It changes it to "Blog Title - Category:NAME OF CATEGORY - Blog Title", which isn't exactly what I want to see, but it's much better than before. Thank you!

Then make it look like this

request_title( array(
	'format'				=> 'htmlhead',
	'title_before'			=> $Blog->get('name').' - ',
	'title_after'			=> '',
	'title_single_before'	=> '',
	'title_single_after'	=> '',
	'title_page_before'		=> '',
	'title_page_after'		=> '',
	'title_none'			=> $Blog->get('name','htmlhead'),
) );
