If you zoom in or out in CAD view it matters where your mouse pointer is on the screen. If you pointer is on the far left of the screen zooming out has a different result then if it were on the far left. This way you hardly have to use your arrow keys to navigate through your drawing. However in the Contents pop-up window of a CAD-item in Layouts, this behaviour is not there. Nor I believe the ability to use the scroll wheel click-and-hold way of moving around. I would like to see this one improved, so navigating works consistently in the whole app.
