Is there a way to reorder siblings?

[npearson72]

In the demo, I can move nodes to different parents, but I can't reorder siblings.

I also had this problem, I made a few changes to the angular-treeRepeat directives to achieve the behavior you can check here (on the "Board" -> lower center of the screen) :

Unfortunately, I never got the time to make a pull request.
You can still check out my code here :
