Codejock Software's Docking Pane allows you to change the direction that the docking pane caption will be displayed. The pane captions can be displayed vertically or horizontally. This allows you to display the caption in the direction that best fits your application. You have the option to always display the captions vertically or horizontally, to change direction by position which will display the caption horizontally if the pane is docked to the top or bottom of the application, and to display the caption vertically if the pane is docked to the left or right of the application. You can also change the direction by the size of the pane which will display the caption horizontally if the pane's width is smaller than it's height, and it will be displayed vertically if the pane's height is smaller than the pane's width.
Both horizontal and vertical caption directions
