Hi, My suggestion is: Take away the editor for formatting (it only makes it more complicated and unstable ). Keep the validation function and text fill-in functions. Create clear and for everybody understandable CSS "rules" / "styles". Write a great tutorial about Form-Builder and CSS and you save 2/3 of the code in the forms now.
It's a great way for people to learn CSS and to find out that it works 5 times faster then the editors formatting functions do at the moment.
