I have two questions:
I hope you are well today and thank you for your questions.
How can I edit the footer so that I can keep some widgets but not others?
You can edit it from the Footer Widgets area as shown in the attached screenshot.
Also, where can I go to edit the footer information?
Edit it from the theme footer settings as displayed in the second & third attached screenshots.
How can I add different sections above/below a blog? I currently like the “Mix” layout but that option is only available if the entire page is set to be a blog and I am unsure of how to add other sections above/below it.
Currently you have to develop custom code to achieve this.
I have added this in the feature request so that it will be implemented in the future version of theme.
