Category/Taxonomy Unification

Hi Community,

I am building a website on wordpress and have been looking for a way to unify categories and/or taxonomies withing wordpress.

To be more clear, I would like to unify the categories and/or taxonomies for everything within wordpress, that is Posts, Media, Testimonials, Clients, etc.

Is there any kind of plugin or script or anything else that will allow me to do something like that?

I’d be very thankful and grateful to whoever has a positive answer to this :stuck_out_tongue:

Thanks already!
