Rating: 5 stars

I’ve tried a few media library plugins with varying levels of success, but they all did far too much for what I needed, which was simply to add categories and tags to attachments. This plugin does that and, more importantly, inserts filter select dropdowns in the appropriate places throughout WordPress, including the media modal interface.

Adding taxonomies to attachments isn’t hard in WordPress for developers, but dealing with the media modal interface can be a real head-scratcher, so this plugin is worth it for that alone.
