Hey thanks for the question. The premium Tab Manager plugin allows you to create new tabs with static/html content, supports shortcodes, and also has a variety of filters/actions so that dynamic content or integrations could be performed if you have some programming ability. It also allows you to re-order/re-arrange tabs added by other 3rd party plugins, such as the WooCommerce Product Enquiry Form.
So, the Tab Manager won't necessarily allow you to put content from some other plugin into a tab, unless that other plugin provides a shortcode which you can use or you have the programming ability to use our plugin's filters and pull the content out of the other plugin.
I hope this makes sense and helps
