Disable Site Search
Turns search off: search URLs return a 404 page, the search form is emptied and the classic Search widget is removed.
Snippet Library
Disable Features snippets for WordPress
Snippets that switch off WordPress features you do not use: comments, the block editor, RSS feeds, automatic updates, attachment pages and more. One snippet per feature, so you turn off exactly what you want and nothing else.
Turn Off the Visual Tab in the Classic Editor
Makes the classic editor open in Text (HTML) mode only, for sites where the visual editor keeps changing hand-written markup.
