new window opening

Hi there!

Please, improve the new window opening to such a procedure:

When we are clicking twice some camera in the Nx cameras' tree, it must open in a new window. But if we are dragging the new camera from the Nx cameras' tree to the window with opened camera, the new one camera muct replace not needed one. It is a many times a day needed option, logical and right for the camera choosing process...

Thanks a lot!
