Open one child per node at a time

[stuaylward]

It would be nice to see a configuration option that allows you to have only one child node open for any parent node at one time.

• single node
• parent node1 (open)
• • child node1 (closed)
• • child node2 (open)
• • child node3 (close) - If we open this, child node2 closes automatically
• parent node2 (closed)
• parent node3 (closed) - if we open this, parent node1 closes automatically (and all its child nodes)

that sounds like a solid feature, will get into it once I got a chance. Thanks for the suggestion!
