The dialog says it's asking because of the time it will take to make the changes. But the time with a modern computer is insignificant.
If the real reason is safety, doesn't "undo" take care of that? Undo has always worked for me when, e.g., MC does an auto-import in the middle of a tag change and messes everything up, or when I mess things up all on my own. So what is the downside of being able to turn this off?
I'd be delighted with: (1) being able to turn it off forever, if undo still functions; or (2) letting the user set a higher limit than current one. The current limit is always invoked when changing, e.g., universal tags in a 10-disc set. (Not so rare in libraries of classical music lovers.) Being able to turn this off per session would still be an improvement.
Thanks,
Mike
