Hello,

1. Our theme metaboxes created for specific post types only. To apply them for your custom types, you will need to customize the file inc/classes/Metaboxes.php.

2. Unfortunately, there are no such options in our theme. You can specify the header layout globally of for particular page in Dashboard -> Pages.

3. Try to disable the SKU search in Theme Settings -> Header -> Search and measure the search speed without this option.

4. You just need to clear all the cache after the update.

5. Enable the icon in Theme Settings -> Header -> My account links.

Regards
