@Borewit: Re listFix() v2.4.2:

I am not at all sure about this, but selecting "Find Exact Matches" to fix a broken list appears to not deliver what resembles a result, or flag a clue of some sort. It does briefly display the progress window, though. Screen video below.

In addition, do I post any questions etc, I may have about the app in general, here under issues, or perhaps elsewhere?

Thank you.
