That one seems to work only half-way (Okay, it's a flag ): Cycling itself does work OK AFAICT, but closing a tab will not obey that order (I don't know it that's ever been given a thought, but one without the other isn't working for me)
The flag only covers tab cycling because that is all it was ever designed to do. Closing order is a separate issue. It shouldn't be the same flag or setting anyway because not everyone wants both.
