<p>With current hook_nodehive_sidebar_nav_items_alter we can only add items under "Content" group in sidebar. Would be great to allow also adding new groups.</p>
<p>See images. MR comming soon (only one line added),</p>
<pre>\Drupal::moduleHandler()->alter('nodehive_sidebar_sections', $section_definitions);</pre>
