While I am thinking about small and not too far-reaching nice-to-haves: how about a "cascade popups" entry in the view menu that takes a scattered set of pop-up windows and forcibly stacks them at top left? I always lose things like the view controls if I move the window about and going through the process of figuring out where they have gone is needlessly fiddly.
I also think the View Control palette is a P.O.S. visually - the two arrow icons don't properly represent the effect they produce. A bit of 3d here in the graphics would be easy to do without impacting the code...!
