I need to limit users options when they put links. On the popup form they should be able to enter only URL other option should not work for them or got disappeared. And I would like to default it to a target=_blank  rel=nofollow .

 Same Thing with Image upload just brows for user and default setting for image size etc.

 How would I do that ?

 Also how would I get rid of HTML view button and Preview Button do not want to give users ability to view it.
