For walk cycles, you currently tag your Body "views" using the same Head profile "views" tags as you use for the Head Turner behavior. I think that's a confusing / non-intuitive rigging step. It would be more obvious if you were using a tag that looked like a body facing right or left when tagging your Body views.
I read in the forums that CH knows the difference even if you have Head views tagged for Head Turner and Body views tagged for Walk, b/c "Walk only actually uses the views that have some Body-tagged handles." But I think it would be more intuitive for users if there was a separate Body view tag for right and left profile, instead of having to know to use the same Head ones but apply them to your Body-Level layers in your puppet.
