I was wondering if it's posible to only change the editorbody width and not the whole editor?

Since i'm using the editor to let users edit a sidebar item (only 200px wide) but if I set the editor's width to 200px it will be very high with all the buttons filling a lot of rows.

 

I have the space in the editview (seperate page) for a 600px editor, I just want the user to see that they only have 200px before a linebreak occurs!

 

Actually, I just noticed that my editor won't even become 200px but stays 225px since thats how wide the buggest group of butons is:
