Advanced Mode with No Right Pane?

Recuva has an option to choose Advanced, but no way back to Simple - and no way to close unwanted right pane, as needed to maximize horizontal space for long filespecs etc.

I understand if once "Advanced", can't go back to "Simple" as settings differ - but that should not force the right-hand preview pane without a way to turn that off (resizing down partially is not enough)
