I had the same ask as well, to have the title go all the way across and then begin columns. I couldn't find a good workaround with my current version ... I even tried just duplicating the widget and leaving it blank but you still get that noticeable break ... I've noticed my users generally don't seem to mind the short title bar if there is another visual or more interactivity in that space to distract them and not just white space, e.g. in the case where there is a Tabber or a map in the top right corner and not an indicator ... food for thought!
