Sorry PeterPoll, this would be the new feature for the theme so you really need to hire a developer to customize the code for you. Also please make the child theme first before you customize the code so that you won’t loose the customized code when updating theme to a Newer Version In future.
No we are not going to include this soon in our further Updates. We meant to say that the requirement that you described was not possible to do just with the Custom CSS. The Theme Core code should have to be customized so we said its the new thing for the Theme.
and Thank you for appreciating our Theme and please let us know if you have any other queries regarding the Theme.
