JabRef should, if necessary, warn about changes to the "citationkeys" that have been added to the files!

[NeymanDmitry]

The directory marked as "Latex file directory" contains many documents that can be linked to the library through existing citationkeys.

A simple change in the rules of citatiokey formation in the program leads to the loss of relevant links in the relevant TeX documents.

So you might have to fix hundreds of links manually!?

Suggestion for improvement:

Each time the citation key is changed, it is necessary to automatically check whether this citationkeys are included in the documents corresponding to the Latex file directory. If they are included, there should be at least two possibilities to change the citationkeys data in the documents, the default action and rename automatically.
