KDA Custom Editor Buttons

KDA Custom Editor Buttons lets you define your own Classic Editor controls:

• Wrap selection in any tag / CSS class
• Insert HTML templates (e.g. definition lists)
• Add a class to the current block (optionally with a tag)
• Open a code snippet dialog (language, line numbers, edit in place)
• Show each control on the toolbar, in Formats, or both
• Limit buttons to selected post types (including custom types such as articles)

Front-end CSS still belongs to your theme if you want a custom look; the plugin ships a neutral snippet window, Copy, line numbers, and token colors. Prism.js and Highlight.js are bundled, so nothing is loaded from a CDN. The admin UI is English and can be translated through translate.wordpress.org.
