Remove form's box-shadow through the designer instead of CSS injection.

For #4, can you submit it as a feature request? In many cases, when someone embeds a form, they want it to appear to be a seamless and native part of the page and not a foreign object, so there ought to be a way to remove the shadowy border without resorting to custom CSS.

The feature request to remove the box-shadow from the designer instead of CSS injection has been submitted to our back-end team. If there is any progress with this request, you will be notified via this thread.
