It would be great to have more control in design studio. ... (not every body is a developer)
1. be able to set the radius size on rounded corners.
2. be able to set the submit buton or call to action button in the same row as the form fields ( In line ) and responsive in design using percentages and max-width....
3. it would be great be able create your own buttons with more custimized styles (css3 color transitions, personal images....)
This sould be able to be done with in the design studio wysiwyg app.
This would be very useful for a company, so that they could keep the form in line with their brand
