BB,
As a vendor, I have made a lot of mistakes when trying to push the envelope. It is devastating.
I used to show horses. When I got thrown off the horse or lost a competition my mother always instructed me to get back on the horse saying I could only quit when I got it right or won. I became a champion horsewoman because of it.
    You are doing something very complex. Something no one else would take on. So, it is not perfect the first time. You are still a champion and will push the envelope for all of us. You will bring out a fantastic new library soon. It will be way better than the old one because now you know want users really want. In 3 months all of this will be forgotten.
Steady on my friend, you will overcome.
