I hope I'm posting in the right place for this question about 2.0 beta:
How do I widen the posting area?
I've hunted all through this forum and cannot find a solution except for trying in the Display.template.php, but I couldn't find where I could do it in there. Any help would be greatly appreciated.
'width' => isset($editorOptions['width']) ? $editorOptions['width'] : '70%',
You can change the width to any percentage or pixels you want.
