Oxygen Builder's editor has a dropdown in the top bar called "Back to WP" with two links: Admin and Frontend. By enabling the Back to WP Links extension, you'll find a new tab in the Editor Enhancer admin to another admin page. On this page, you can select options to add your different post types and general WordPress admin links. Each link is added below the original two. Click the name to open the link in the same window, or click the external button to open in a new tab.
