Based on Monster Widget, this plugin consolidates all BuddyPress core widgets into a single widget enabling theme developers to create multiple instances with ease. It has been created to save time during theme development and review by minimizing the steps needed to populate a sidebar with widgets. This widget is not designed for use in production.
BuddyPress widgets included:
<ul>
<li>Log in </li>
<li>Members</li>
<li>Who’s Online</li>
<li>Recently Active</li>
<li>Friends</li>
<li>Groups</li>
<li>Sitewide Messages</li>
<li>Recent Networkwide Posts</li>
</ul>

Provides a quick and easy method of adding all BuddyPress core widgets to a sidebar for testing purposes.
