We also improved the theme to handle the things in the review such as: removing default style for the 1st paragraph, increase font size for the post content (and add a dedicated font options for post content to customize it separately from the body).

Just a small note: the Full width page template has the content area 100% of the screen width, while the Wide page template has the content area 100% of the container width. They're both useful for creating landing pages.
