I don't like the new Pop up window, only because on the Note 3 you could change the aspect ratio of the window on all sides. This new one can only be a long rectangle and it gets in the way of the app behind it, so you can't make it a square or smaller than the smallest size it's able to now. So for me it just gets in the way. Drawing it before, I can resize sideways, from the top and make it the size and shape I wanted.
