provide a switch to Hide/Unhide posts. or fix Re-Publish
based on actual experience I had this idea. I found some of my old posts filled with broken URL links to fix these errors would take time, that I hadn't at that moment missing a HIDE switch I just unpublished it. Re-Publishing marked it as NEW. No problems so far. But all replies ( 6 years old) popped up creating a strange timing pattern: - looks a bit like Marty McFly, Back to the Future
With a HIDE/UNHIDE flag the publishing date should not be touched:
Alternate solution: Fix Publish action and set it only if there is no previous publishing date yet.
