Users with access to more than one group can click “Your Group: …” on the toolbar to switch groups. If there are certain groups your editors use frequently (for instance, the Homepage, Newsroom, or Marketing groups) you can configure those to appear at the top of the list.
Simply add the following to your livewhale/client/global.config.php file:
$_LW->CONFIG['TOP_GROUPS']=[123, 456]; // array of group IDs
Not sure of your group ID? Hover over your current group’s name on the toolbar and the ID will appear as a title/tooltip.
