No I never got around to putting that back in to the v2 code. It should be fairly straighforward to do, because there's a user control for drawing networks/genomes (used by the 'best genome' view) that can be re-used.
Take a look at how the best fitness view/window works (GenomeForm.cs); make a copy of it with a different class/file name. The species are all in NeatEvolutionAlgorithm._specieList.
Each species has a list of genomes, the first one in the list is teh fittest genome in that species; I figure that's the one you want to view of screen.
