Most of the user interface elements in TrueMap can be floated or docked within the program's client area.

 

The Surface Windows are the windows that render the surface data in the 3D view.  When in the tabbed mode, these windows can be dragged and docked to any side of the client area.

 

 

Surface Windows can be moved to the next group of tabbed windows simply by dragging the tab into the target window.  This can also be done by right clicking on the tab of any window and using the context menu.
