Taxonomy Terms Counter

Description

Taxonomy Terms Counter adds term counts to taxonomy panels in the Gutenberg editor sidebar.
You can enable or disable counts per taxonomy and post type from the plugin settings page.

Source Code

Full source code is available on GitHub:
https://github.com/secretlab48/taxonomy-terms-counter

Notes:
– The settings page lists only HIERARCHICAL taxonomies. Non-HIERARCHICAL taxonomies (for example, post_tag) are not supported.
– The plugin works only on admin post screens that use the Gutenberg editor.
– The plugin does not work with the Classic Editor.
– If an existing post type is missing on the settings page, it likely has show_in_rest set to false.
– If a taxonomy is missing for a post type, it likely has show_in_rest set to false.
