New Form Layout: "Custom CSS" tab in configurable list widget

I can't see the "Custom CSS" tab. Any ideas?

Thank you for contacting us.

The custom css tab is not supported in our new forms layout. I have forwarded a ticket to our developers to see if this is something that can be added.

We will let you know if we have any updates on this.

Please note that we decide to investigate why our users need CSS option on JotForm Cards. That’s why, we would like to know more about why you need CSS option for the JotForm Card?  Which styles you want to change and how? We respect our users concerns and try to serve them in a better way. If you inform us as much information a you can, we will try to find a way to accomplish your needs.

As we did not hear from your side, we want to send a second notice you regarding your CSS request. We would be pleased if you can tell us why you need this feature, to change which styles and how?
