Hello. I did a quick search and it looks like this may have been suggested at least a few different incarnations and I wasn't sure which thread to add my thoughts to so I'm starting a new one...
I added a little system in where there's a drop down at the end of every message for my moderators to use when they take some sort of action on a post and want to PM the member about this.
Here's what it looks like:

What I did was quick and dirty and it's a pain in the butt to add/edit these canned PMs. I was thinking perhaps SMF might benefit from a more robust system for this where it's easy for the Admin or Global Mods to add and change the canned messages available.
Thanks for listening!
That's not a bad idea at all though I suspect it won't make it as a feature BUT I think it would make one heck of a modification.
