YITH WooCommerce Tab Manager

although the interface is barebone... I can manage with some simple h and p, does it job :)



working, just what I needed

This plugin name is misleading.  It adds a single tab globally (same content on all products) to every product. I guess its useful in some limited cases.

While I'm a fan of plugins with simple focused use cases, YITH WooCommerce *Tab Manager*, really does nothing to *manage* your  tabs.  "YITH WooCommerce Add One Custom Tab Globally" would be a better name for it.  

I'm left to the conclusion this plugin is solely to upsell people to a paid version.

Of very limited use
