Sorry, both sent at once. Great minds think alike. Again, I don't know your situation, but in six years of using the program, no one has ever once said that a sent box would be helpful.
I don't say that to belittle your needs, I just say that to indicate that it may become easier as you go along. One thing you may want to know. There didn't use to be a deleted folder until v4 I believe. That was a huge improvement.
