The JSM's Show Term Metadata plugin displays term (ie. categories, tags, and custom taxonomies) meta keys and their unserialized values in a metabox at the bottom of term editing pages.
The current user must have the WordPress manage_options capability (allows access to administration options) to view the Term Metadata metabox, and the manage_options capability to delete individual meta keys.
The default manage_options capability can be modified using the 'jsmstm_show_metabox_capability' and 'jsmstm_delete_meta_capability' filters (see filters.txt in the plugin folder).
There are no plugin settings - simply install and activate the plugin.
Shows Yoast SEO Term Meta
Yoast SEO stores its term (ie. categories, tags, and custom taxonomies) metadata in the WordPress options table, not the term meta table. The JSM's Show Term Metadata plugin will read and display Yoast SEO's term metadata, but it cannot be deleted (as it does not reside in the WordPress term meta table).
