There have been a variety of requests for control over window order, but this is the first time I've heard anyone suggest duplicating the window. I'm not sure that would be the best option. Especially considering how scripting works with windows right now. It would probably be a lot of work just avoiding breaking scripts. If it could be done in a way that would make sense to the user and wouldn't break a lot of scripts, then it might be worthwhile. Personally, I'd just be happy with a drag and drop method of moving channels around similar to how tabs work on IE or FF (when using the switchbar) and something similar for the treebar as well. It might not offer a "sticky" view, but it would still let you put things in an order that is useful for the user.
