- Scroll wheel now zooms camera (moves along look direction) instead of adjusting speed. Much more intuitive for terrain editing. - Shift+scroll adjusts camera speed (old behavior preserved) - Click on minimap to teleport camera to that location on the terrain - Zoom speed scales with current camera speed for consistent feel
