Disable the Admin Bar for Everyone
Hides the front-end admin bar for all users, including administrators. The admin area is not affected.
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.
Disable the Admin Email Check Screen
Stops the periodic "Administration email verification" screen that administrators see after logging in.
Hide Admin Notices From Non-Administrators
Removes plugin and theme notices, update nags and promotions from the admin for everyone who is not an administrator.
Prevent Switching Themes
Stops anyone, administrators included, from activating a different theme, so a client cannot change the site design by accident.
