WP Site Links

Allows easy access to all of your posts, to reference while writing.

NerdCow

The plugin adds an additional field below the page title on the page edit screen. The value from that field acts as an internal page title that is only visible to back-end users. Thanks to this you can have a user-friendly page title for your website visitors while keeping a separate page title that is obvious to your editors and administrators.
For example, you could have a form submission thank you page with a public title that reads “We look forward to speaking with you”, but keep an internal one that says “Contact us – thank you page” without affecting what front-end users see.

Internal Page Title

Adds the internal page title for organisation use.
