I received the email announcing version 11 today.  I have not used this product (V10) at all yet as it is not possible to design a responsive website with it.  As far as I can tell V11 does nothing to change this so I won't be buying the latest version.  I'm amazed that such a basic requirement for all serious sites is left out.  I am posting this in the hope that someone can show me to be wrong as in all other respects this is a fine product.
