Web designer in large Marketo instances sometimes grumble about local marketing staff not complying with styling guidelines. One of the point in question is the non respect of recommended choices with regards to form themes.
I would love to be able to restrict which form themes are available to users in the instance and hide the undesirable ones.
Yes, I agree (and I had voted already), but I just felt that limiting the choice of themes would be an easier first step towards better control of what users are doing
