This feature request has now been implemented in the latest V5 version! That release has an entirely new rendering engine with new 3D view controls that should be far easier to use. You can customize how the zoom and rotation work (centered around models, center of platform, nearest part, etc). Zooming can also go towards the mouse or the center of the platform if you prefer the old V4 behavior.
From using V5 internally I can tell you it is quite a significant upgrade in terms of how quickly you can move around the 3D view. Thank you for the great suggestion!
