Controller appearance

Except for the background colour difference, the default controller blends right into the form it abuts. When I add a custom controller a frame goes around both the form and also the controller.

Are there settings to allow a smooth integration in the style of the default controller?

Answering my own question.

Set top, left, and bottom border property in the custom controller, set the top, right and bottom border of the main form. :oops:
