Taxonomy Terms Counter

Description

Taxonomy Terms Counter adds term counts to taxonomy panels in the editor sidebar for both Gutenberg and Classic Editor.
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:

Notes:
– The settings page lists taxonomies that are available in REST for the selected post type.
– The plugin works on admin post screens for both Gutenberg and 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.
