I was looking for some workaround to cut some of the Rich Text Editor default features.
I need for instance just bold and italic.
Also, is it possible to get somehow the plain text also? I know I can use .getValue() and get rid of html tags but I was looking to a more straight forward method to do it.
As a workaround you could try to hide buttons via CSS, using icon-id attribute of buttons. For instance, italic button has icon-id="richTextArea.italicLabel".
