With the ABB Flex Theme you not only have the ability to style or add/remove some features within the theme options panel, you also have the ability to add/remove some of these features on each post.
Author Box
You can choose whether you want to display an author box on all posts or display none. If you choose to display the author box on all pages you still can disable it from showing up on each post.
Google Adsense
This is the same as with the author box. You have the ability to choose to display adsense ads on all posts/pages but you still have the ability to disable that feature on each post/page.
Rating Box
You have the ability to include a custom rating box on each post. You can read more about it here.
