Hey Craig,
I’ve made the necessary changes to the code in order to implement items 1-4; note that 3 and 4 were not envisaged by the theme initially, I’ve made slight customizations in the “search.php”, “single.php”, and “style.css” template files in order to implement them. Please review and let me know if everything is working as desired.
Sincerely,
Andrii / Satoti Studio
