I am currently learning how to use the Docking and actions framework you have made. I was wondering if it was possible to beeing able to drag and drop CommandBars into the CollapsiblePanes and visa versa. I would like this feature instead of dragging the toolbar to the side and creating a vertical toolbar.
My current setup has toolbars at the top or bottom, and a CollapsiblePanes menu at the right hand (like in your demos), I'd like the ability to drag and drop a commandbar from the top to the right hand and then create a CollapsiblePane from a CommandBar. Also beeing able to rearrange the CollapsiblePane's inside the CollapsiblePanes would be great (using Dockable handling with drag, drop and outlining).
