Sent Messages Box

[#1]

Just sent a message and checking the folders the setup is a little different to what I am used to.
Normally there is an Inbox, Sentbox and Outbox (also a Savebox in the old forums) but in this forum there appears to be only an Outbox and an Inbox.
Is this a change of policy where there is no indication when the post is delivered.
In the old forums this is when it goes from the Outbox to the Sentbox or, if not saved, is deleted.

I've seen comments on SMF not letting you see when a message has been delivered - but I think on PUG not here. It's the only significant thing where I think phpBB is better than SMF.

You don't work for Microsoft do you 
If it can be done by an add-on I think it would be a good feature

Any use?

It's not a properly packaged Plugin, so it's unlikely to be used.

Surely a man of your calibre could make it in to a properly packaged plug-in?
