Recently I dusted off OG Vocabularies with an eye toward integration with OpenAtrium. To my mild surprise, there was really not much that needed to be done. The menu path (node/%node/og/vocab) isn’t great, but that can be tackled later.
All I wanted was to avoid another hidden tab that can only be reached by clicking on Settings > Customize Features. I wanted the group vocabularies to be accessible directly in the Settings menu.
