Switcher

Switcher adds one icon button to the WordPress toolbar. On an admin page it opens the public page you viewed last; on a public page it opens the admin page you viewed last. Before you have viewed anything it opens the home page or the dashboard.

• No settings, no extra files to load, nothing stored on the server.
• Two cookies in your browser remember the last page on each side for 30 days (switcher_public_url, switcher_admin_url); they are set with the Secure (on HTTPS), HttpOnly and SameSite=Lax attributes.
• Only real page views count: not AJAX or REST calls, feeds, embeds, 404 pages, previews or form submissions.
• The button only ever opens an address on this site.
• Keyboard shortcut: Ctrl+Alt+S (also on a Mac) switches sides without touching the mouse; it is ignored while you type in a field. The tooltip shows where the button leads.
• Works for every logged-in user who sees the toolbar; visitors get nothing.

Developers: switcher_cookie_lifetime filters the 30 days, switcher_cookie_options the arguments passed to setcookie(), switcher_shortcut the key combination (return an empty array to disable it).
