It gives for free what others charge for!

The rest charge you for the ability to assign tabs to a specific category and here you get it for free. The only thing I would mention is that sometimes setting the order of the Tabs is not as clear as it should. It can happen that the default Woocommerce Tabs like “Description” has a priority different than 0, so you just set the Priority to a very high number like 30 or even higher, until your custom Tabs apear after the default ones.
