After release of WordPress 2.5, the IDs on all admin pages have been removed as it was, probably due to the fact that the common user don’t need them. However, for advanced WordPress users / developers those IDs were quite interesting for some plugins or template tags.
What this plugin does is to display IDs on admin pages, showing the IDs, as it was in versions prior to 2.5

This plugin adds additional advanced inspector controls to Gutenberg blocks that allow to add any custom HTML attributes to the block’s front-end output. This allows you to add inline styles to fine-tune the block’s appearance, set aria attributes to improve your site’s accessibility, add data attributes to integrate with any JavaScript modules or even JavaScript DOM event attributes such as <code>onclick</code>, <code>onchange</code> or <code>onload</code>.
