on Menu page, turn posts by default on "view options"

[itailulu]

Right now posts box is not shown by default,
This creates confusion (I've seen it multiple times with my clients), and often times leads users to create custom link entries, which is superior by far (it doesn't sync if you change the post, etc)
There should at least be a notification about this issue, if not enabled by default.

Seems like we could remove nav-menu-theme-locations from $initial_meta_boxes, since that does exist anymore, and add add-post. If somebody wants to investigate why Pages ends up showing last in screen options even though it's at the top of the meta boxes (probably deserving of its own ticket), that would be nice, too.

I uploaded a patch to make the suggested change. I'll also see if I can look into why Pages is last on the list and if it is a small/quick fix I'll add it here, or if it's more complex then I'll open a new ticket for it.

New ticket created for the ordering of items:

(I tried to figure out what is going on and I got a little bit lost trying to hunt down where global $wp_meta_boxes; is set because that's where the order is being set)

I think you answered it yourself after [32707]. :)

In 32842:

Show the posts meta box by default in Appearance > Menus.

Lessens user confusion and the likelyhood of misusing custom links
to add menu items for posts.

Props bcole808.
Fixes #32440.
