Add a preference selection button for navigation that allows the user to enable re-centering of the graphics window to the mouse tip when zooming with the scroll wheel. This will allow simultaneous pan and zoom moves with just the scroll wheel. This is a common navigation technique in other CAD platforms. Its absence is driving me crazy.
Works like this:
Need to pan to the right to re-focus on a different object, move the mouse to the right part of screen, scroll out. Window re-centers with each scroll click, and effectively pans while zooming out. Once object of interest is on screen, locate mouse tip on object and start scrolling in, object of interest moves to center screen, adjust mouse to follow object, continue scrolling until desired zoom is reached.
