Adding a tab to commons browsing widget with hook_commons_bw_group_widget() I am trying to add a tab to the Commons Browsing Widget so I made a custom module and followed this guide https://drupal.org/node/1782922. I used the first PHP code with hook_commons_bw_group_widget() but it doesn't add the new tab to the widget. What could be wrong?
Don't know if this is your module, but this one accomplishes just that:
