This enhancement is a part of the August 7, 2021 release.
The Hidden option in Page Properties is now a dropdown of options to hide from menus, including a new option to Hide from mega menus only. This will give users even more options to balance their mega menu columns.
This dropdown has replaced the previous series of checkboxes for Hidden and Show in Sitemap. "Hide from all site menus" has replaced the Hidden option. "Hide from all site menus, but show in site map" has replaced the Hidden with Show in Sitemap option. "Hide from mega menus only" will only hide pages from Pages widgets or mega menus, but not secondary navigation or the site map.
