Add permalinks to the document sidebar

[karmatosed]

The current problem is permalinks aren't that discoverable. This has been reported in feedback. Right now, the title on select show the permalink. In phase 2 this likely won't be a case moving into everything being a block, so changing now is important.

@melchoyce worked on a suggested design for this which adds to the document settings (note this adds doesn't remove from title for now):

• On select of title won't be changing, it will still show permalink.
• Publishing flow will still show permalink.
• This is a new panel to be added to document settings.

This ideally would be added before 5.0 as really could help people now. It is based on the existing pattern in the publishing flow, which means it should be easier to implement.

One feature that may want to be added is the ability to copy the link from here easily.

As time is of the essence having this move into a PR would be great to get a feel of this.

What about custom post types? Should it be included, too? I'm asking because it contains distinction between page and post.

My plan is to use the singular CPT label, so it will "Post Link", "Page Link", "Book Link", "Movie Link" etc...

Yes, should use the provided and localized CPT label.

I really like this solution as it makes the permalink settings more discoverable. The "preview" link below the field also clearly shows the output of the setting for users.

Should the label be "Post Slug" since it's not actually showing the full URL?

Overall I think this is a great improvement. I'm not sure whether exposing permalink settings there is necessary but unless there's strong consensus one way or the other I'll go with the group :)

Love this proposed change. Permalinks have been a bit hard for me to work with.

What happens when I click “permalink settings”?

"Slug" isn't a super friendly term for non-technical folks. I reviewed Wix, Weebly, and Squarespace, and they all use some form of "URL," even though you're just editing the slug.

Takes you to options-permalink.php.

If the permalink is moved to the document sidebar, can the title be as well? When trying to build a wysiwyg experience, many times the title is not the first thing on the page, so you end up with a not-so-wysiwyg experience because you have a title above the content but it appears as if it’s part of the content and it’s just confusing from a wysiwyg standpoint.

The title should be a property of the document, and should be able to be placed in the page where it makes sense to be placed, often below images or carousels or other leading elements.

Sometimes the title isn’t even displayed on the front end at all.

Let the document properties be document properties and the editor be for editing.

Discussed here back in April too.
