[TYPO3-rte] Changing width and height of htmlArea RTE workspace

[David Schreiber]

Hello everyone!

When I edit content in TYPO3-BE with htmlArea RTE, the workspace of the 
editor stays at 530 pixels width, even when I resize my browser window to 
fullscreen. At the right side of the editor there is a empty space about the 
size of the editor itself.

How is the size of the RTE editor window defined, and is it possible to 
change the size (eg. to full width).

Thank you in advance,
David Schreiber
