+1 to remove this option from the editors since it’s displayed in a lot of use cases when it’s actually rarely used by simple users. I can imagine new or non-techsavy users not understanding what a hidden page is, or even accidentally ticking this box when editing a page and wondering why the page disappeared.
+1 to remove it from the information panel too to keep consistency.
Actually, not exactly. This proposal is only about setting the hidden field. Simple users would still be able to view hidden docs (if they configure it in their preferences).
