Form styling features should be deactivated or subject to a role.
Situation: you created some marvelous templates and added all the required CSS to manage the form endering, yet a "smart user" gets into Marketo and modify the CSS of the form in the form editor, changes the default font, etc... breaking all your work.
It would be interesting to be able to deactivate all form styling features, starting with the choice of the theme and continuing with the form font and size, as well as the label position and continuiing with the form custom CSS. A simple checkbox in the admin would suffice.
