Often when I work, I need two independent screens up to reference a previously reviewed document or bring pages from one doc to another, and I am really handicapped not having two functional, i.e., fully tool laden windows to work with. This floating window off to the side with nothing but tabs at the top is virtually useless. I know it's active if you touch it, but all the tools and thumbnails are only on the one main window. If this is supposed to be a differentiator between you and Adobe, then it sucks as a premium feature. I'd argue it's not a feature at all, it's an undeveloped thought at the moment. Just like any other successful program out there, when someone drags a tabbed doc of the main window into another screen, then bring all the tool bars with it.
