   Format: Markdownadded to [[crossed complex]] a section <a href="http://ncatlab.org/nlab/show/crossed+module#Morphisms">Morphisms</a>. Also single out in the Idea section, among the list of 50 or so different ways to look at a crosssed module, the [[nPOV]]-perspective to the top and highlighted it. Because: Nothing in biology makes sense without the theory of evolution, they say. Nothing in math makes sense without the nPOV. (I'll add this statement now to [[nPOV]] :-))

   added to crossed complex a section Morphisms.
