Many times, there is a suggestion in the forum to have a user reset the preferences, as it is known to cure many issues. Unfortunately, it sometimes does not work, and the user has to recreate them manually.
In addition, the preferences file, once deleted, is not available for troubleshooting by the Ps team.
(in the forum, I now suggest the manual method of copying the folder to the desktop to keep a copy.

I think that it would be beneficial to every user if the reset preferences function, either by shortcut, or via the preferences, would instead zip the existing preferences folder (or maybe just suffix it with "old" (or the beloved "legacy" term used all over the app.) In addition, it could also include the system information text.
This way, it would be possible to troubleshoot preferences and have system information in one go, and the user would be able to revert them easily.
Another idea would be to create a backup at startup, to get a last known working preferences file and a way to revert them, like we can use a backup firmware in some cameras.
EDIT Thanks to @Stephen Marsh he has coded a script, that, IMHO, should be integrated in the application itself!
