Conversation trees works pretty bad with the current layout, javascript etc. So it's best if we separate it and work on it as a side-project. The oldschool settings are currently being deprecated (or broken out like this). I'll wait with removing User preferences for oldschool conversation tree, since that might be reusable data. But I guess it will go in the near future.
