You have used a jumbo responsive video on your demo page. I am wanting to achieve this effect but can't find the appropriate plugins and/or theme to do this.
I initially submitted this ticket and was not able to accomplish this. However, you theme builder is so intuitive that I found the answer within 1/2 hour. This alone is a super time saver based upon other drag and drop builders where I have spent the better part of a day trying to find out how to do this and 3 weeks communicating with the support staff.
I wanted to write this to give your team an A+ -- I have been using the tool for less then 3 hours and have created two top level header image themes of fabulous quality. Something I was not able to achieve with your competitors in a day or even a week!
