[i]actually, in my version (1.4.6 last release before the upgrade), the pages with password appear with the printPageMenu() function.[/i]
You are right, my fault testing sideways… The page I tested with quickly was unpublished accidentally. Indeed they do. Is unpublishing maybe an easier option for your? People still could access them by direct link then and users with full or pages rights should see these if being loggedin.
Btw, you could open a ticket on GitHub suggesting this, so we may add this as an option in one of the next releases.
