Registered a custom post type (xyz) and after that added a meta box using this excellent Tuts+ tutorial, so then I can reduce the usage of ‘Advanced Custom Fields’ where I can (but I love ACF most). But doing so, I came up with some questions:

  1. What is the difference between 'high' and 'core' in the $priority parameter?
  2. How the 'normal' and the 'advanced' are different from each other in the $context parameter?
  3. However I added a meta box it showed a Standard meta box with sortable field-group. How can I achieve an Embedded-like meta box (as how ACF provides with 'Seamless') so then the field-group embeds on the body and user can’t sort ‘em as their wish? Is that only a CSS issue?
  4. If I think to provide boolean false to 'supports' parameter when registering custom post type (CPT) and make meta box with meta fields to the post type to get the data - is that good for all causes - whether a data hierarchy, SEO, and so on?
