Hi, i've never addressed this until now as i see it as a rather low priority issue. But now that multiple planets become more and more of a thing it becomes very obvious just how bad the zooming works on MacOSX. I believe the problem lies in the inherent "inertia" of scrolling on MacOSX, while that is great if i want to flick through a website in a browser, in PA i want zooming to stop as soon as i stop zooming. As it is now i have to set zooming speed to 1 to have any kind of control about where the zoom stops. I'm pretty sure this "inertia" can be disabled for a specific application, so if that's really the reason please do so!
