I've audited again the plugins I've used on this site. I've removed the following, but not because they aren't useful (they are), but because I don't need them right at the moment:
- Enhanced Media Library
- Originally used to improve the functionally of the Media Library, but since outclassed by the Media Library Assistant plugin.
- Custom Post Type UI
- Used to prototype the custom taxonomy I use to identify and the photos and images to which I'm the sole copyright owner. Doesn't need to be installed since I copied the taxonomy into my child theme.
- Updates API Inspector
- Used to get a view on what wordpress does to identify and install updates to plugins and themes. Doesn't need to remain installed once the investigation is completed.
