In the the content editor, you can create a blog listing page that displays all your blog's posts. Only listing pages that use themes or have drag and drop areas support adding or moving modules in the content editor.
Blog post templates must be edited in the design manager instead. This also applies to blog listing templates that have not been opted into editing in the content editor.
