Headway has multiple metaboxes available in the add/edit post/page screen. Here is your reference for what they are, what they do.
Identifying the Metaboxes and what they do
Easily assign a shared layout to a post or page (or custom post type if you’ve added the functionality) when you add the post/page or when you edit it.
You need to create the Shared Layout first in the Visual Editor before it will show up in the drop down list.
Remove a shared layout by selecting “Do Not Use Shared Layout”.
By default, the dropdown should show “Do Not Use Shared Layout”.
Featured Image Position
Choose between Left or Right and Above Title or Above Content.
Easily add custom css classes to this entry that you can then use to target in your CSS to style this entry differently than others.
When using Headway for SEO, here you can control the SEO settings for the specific entry.
Use this to hide the title on different views. This removes the HTML that outputs the title rather than hiding it with CSS.
Use this to change what title shows up in the content block. For example, you could use this to have a shorter page title that actually displays on the page while keeping a longer page title in WordPress and in the title tag in the browser or vice versa.
You may need the different metabox IDs if you want to add the Headway metaboxes to custom post types or remove metaboxes from roles or users.
