So whatever happened with this? Was it decried to be an "all on" or "all off" situation?

If it's set to "all off", as it currently is, and those who like saving them don't remember to save them on a per message basis, they are lost forever.

If it's set to "all on", and those who don't like saving them don't remember to not save them on a per message, they simply select all and delete.

Isn't "all on" a better solution? Is it poll worthy?
