That's for the Widget Framework.
By default this has:
1. Clear Sidebar
2. Staff Online Now
3. Members Online Now
4. Forum Statistics
5. Share This Page
6. Users. 2 modes: order by register_date or message_count
7. Threads. 4 modes: New threads, Recent threads, Popular threads or Polls
8. Conditional HTML. Test a PHP expression and display HTML on sidebar
9. Poll (since 1.0). 2 modes: feature poll and recent poll
10. Visitor Panel (since 1.0.6)
11. Recent Status (since 1.0.9)
12. Birthday (since 1.1)
13. PHP Callback (since 1.1)
Some of these are default XenForo side bar items, but you can turn them on/off, move them up and down and you can also add custom widgets by creating your own templates and adding them as a widget.
There's also, in the Resource Manager, some widgets that have been released for it.
But the general thing is, if there's something you want there, it will be possible. If it doesn't already exist then you can create it yourself if you know how or someone here might be able to create it for you.
