I think it is going to be very useful to people. I think it is a new facility, and I have noticed a couple of bugs. I contacted the developer:
"I've found a couple of bugs. I am a retired software tester, so I know what I am talking about. For example, if you have a note attached to a record, and that note has hard carriage returns, the lines are concatenated without inserting a space. Also there are instances of the first line of notes being removed. Finally, I have an unresolved oddity. There is confusion between the two wives of a person. I can't find an error in my data, but your report shows the second wife marrying the man when she is aged three. It is looking at the wrong date."
If I get a reply, I will update this thread.
