Prevent Switching Themes
Stops anyone, administrators included, from activating a different theme, so a client cannot change the site design by accident.
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.
Remove "Private:" and "Protected:" From Titles
Shows private and password-protected posts with their plain title, without the prefix WordPress adds.
Turn Off Avatars Everywhere
Stops avatars from being shown in comments, the admin bar and user lists, saving the image requests.
