Properties Pane

I'm new to zz. I searched around trying to find an answer for this question. My question is, is there a way to dock the properties pane? In the main view area when you right click and select properties, that pane comes up where you right clicked. Then if you right click again, the original pane goes away. Now if you right click on one of your takeoff items in the right side menu, select properties you can make that pane go wherever you want. But it disappears when you right click to select the properties on another item. But, that pane will open where you last moved it. Am I missing something or is there a way to "dock" the properties pane?
