[Update: Nevermind. I updated CBSubs and the menu item now appears]
I'm not sure if I am missing something else, but for some reason I still can't see CBSubs in the admin menu after adjusting the menu module as described in the link. Is there a setting somewhere within CBSubs I need to adjust?
I have set the module parameters as follows:
CB Menu - Show
Plugin Menus - Show
Compact - Yes
