In the meantime I suggest that you don't use Pier-EditorEnh (or
uncomment the part that creates the list of all pages).

Sorry, I'm not sure how to do it. Should it be unloaded or just "switched-off" somehow?
And the second option says absolutely nothing for me --- where to uncomment that?

There are still a couple of issues in some cases. I've committed
various improvements, but I don't know what you are exactly referring
to?
