FAQ Question: Why "global" taxonomy?

Question: Why is the taxonomy “global” and applied to more than one post type?

Answer:

The answer is simple: Our taxonomy is only for organizing purposes if you have to manage many, many templates. It is easy to just enter 2 or more different categories if you use more than one of the supported integrations (and therefore have our taxonomy applied to more than one post type).

It would add a lot of bloat to register a “organizing taxonomy” for every supported post type of an integration. This really makes absolutely no sense in my opinion. Of course, you are free to tweak the behavior of the plugin with the built-in filters or WordPress Core functions, filters, actions and classes. Plus, you can at any time easily register any custom taxonomy yourself.

This plugin here is a “quick and easy” solution: install, activate, organize with categories. Done.
