The tree is fully recreated every time I export my queue and at times I forget to export. So feel free to look at, but basing work on it might not be the bestest idea. Ideally things should find their way into -tip fairly quickly (or get dropped on the ground if they come apart, but that usually goes paired with an email telling you about the borkage).
