By default in the Total theme you can select from various preset “blocks” for your singular blog post design including elements like the title, featured image, tags, author bio, post meta, comments, related posts and more. These blocks can be enabled, disabled and re-ordered.
Go to Appearance > Customize > Blog > Single Post > Single Layout Elemens to tweak your posts to your liking.
For Developers (Adding new blocks): You can easily add/remove modules via child theme modifications. Have a look at the following snippet for an example.
